Given numbers are 634, 400, 494, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(634, 400) = 126800
GCD(634, 400) = ( 634 x 400 ) / 126800
= 634 / 400
= 634
Step2:
LCM(2, 494) = 494
GCD(2, 494) = ( 2 x 494 ) / 494
= 2 / 494
= 2
Step3:
LCM(2, 787) = 1574
GCD(2, 787) = ( 2 x 787 ) / 1574
= 2 / 787
= 2
So, Greatest Common Divisor of 634, 400, 494, 787 is 1
