Given numbers are 634, 778, 730, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(634, 778) = 246626
GCD(634, 778) = ( 634 x 778 ) / 246626
= 634 / 778
= 634
Step2:
LCM(2, 730) = 730
GCD(2, 730) = ( 2 x 730 ) / 730
= 2 / 730
= 2
Step3:
LCM(2, 401) = 802
GCD(2, 401) = ( 2 x 401 ) / 802
= 2 / 401
= 2
So, Greatest Common Divisor of 634, 778, 730, 401 is 1
