GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 646) = 14858
GCD(782, 646) = ( 782 x 646 ) / 14858
= 782 / 646
= 782
Step2:
LCM(34, 752) = 12784
GCD(34, 752) = ( 34 x 752 ) / 12784
= 34 / 752
= 34
Step3:
LCM(2, 124) = 124
GCD(2, 124) = ( 2 x 124 ) / 124
= 2 / 124
= 2
So, Greatest Common Divisor of 782, 646, 752, 124 is 2
