Given numbers are 165, 630, 707, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 630) = 6930
GCD(165, 630) = ( 165 x 630 ) / 6930
= 165 / 630
= 165
Step2:
LCM(15, 707) = 10605
GCD(15, 707) = ( 15 x 707 ) / 10605
= 15 / 707
= 15
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 165, 630, 707, 102 is 1
