Given numbers are 406, 316, 187, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 316) = 64148
GCD(406, 316) = ( 406 x 316 ) / 64148
= 406 / 316
= 406
Step2:
LCM(2, 187) = 374
GCD(2, 187) = ( 2 x 187 ) / 374
= 2 / 187
= 2
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 406, 316, 187, 634 is 1
