GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(754, 756) = 285012
GCD(754, 756) = ( 754 x 756 ) / 285012
= 754 / 756
= 754
Step2:
LCM(2, 686) = 686
GCD(2, 686) = ( 2 x 686 ) / 686
= 2 / 686
= 2
Step3:
LCM(2, 406) = 406
GCD(2, 406) = ( 2 x 406 ) / 406
= 2 / 406
= 2
So, Greatest Common Divisor of 754, 756, 686, 406 is 2
