GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 702) = 11934
GCD(102, 702) = ( 102 x 702 ) / 11934
= 102 / 702
= 102
Step2:
LCM(6, 644) = 1932
GCD(6, 644) = ( 6 x 644 ) / 1932
= 6 / 644
= 6
Step3:
LCM(2, 702) = 702
GCD(2, 702) = ( 2 x 702 ) / 702
= 2 / 702
= 2
So, Greatest Common Divisor of 102, 702, 644, 702 is 2
