Graha Shanti Mantras are Vedic hymns recited to seek the blessings of the planets in order to mitigate their negative effects and promote their positive influence in one's life. It is an easily accessible and cost-free method that can be performed by anyone at any time. However, to achieve the desired results, the practice requires concentration and devotion, as absent-minded and insincere chanting may not be effective.
Brihat Parashara Hora Shastra recommends each Mantra should be recited a specific number of times to appease the respective planet: Sun (7000 times), Moon (11000 times), Mars (11000 times), Mercury (9000 times), Jupiter (19000 times), Venus (16000 times), Saturn (23000 times), Rahu (18000 times), and Ketu (17000 times). BPHS doesn't provide a fixed timeline for completing the chant, so you can choose to finish it in a day, two days, or spread it out over a maximum of 48 days. The Beej Mantras for all nine planets are
ॐ ह्रां ह्रीं ह्रौं सः सूर्याय नमः | "Om Hram Hreem Hroum Sah Suryaya Namah"
श्रां श्रीं श्रौं सः सोमाय नमः | "Om Shram Shreem Shroum Sah Chandraya Namah"

However, it is important to note that reciting alone may not be sufficient and one should also make an effort to live a virtuous life and practice good deeds.
Tips & Tricks
The most commonly recommended number is 108 times for any mantra. Reciting the mantras for 108 times is known as a "Mala". Some people also prefer to chant the mantras 27 or 54 times, which are known as "quarter" or "half Mala" respectively.
You have the suggested number of recitations acc. to BPHS, but you can break it down to one Mala (108 times) per sitting. For example, to complete 7000 recitations of the Sun Mantra, you can chant one Mala at a time, which brings 64 Malas of 6912 times, leaving 88 more to go. It is helpful to use prayer beads or a digital counter to keep track of the number of recitations. While digital counters can be worn on a finger and pressed after each recitation, prayer beads are considered auspicious and recommended by the ancient seers.
