Given numbers are 646, 487, 121, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 487) = 314602
GCD(646, 487) = ( 646 x 487 ) / 314602
= 646 / 487
= 646
Step2:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 646, 487, 121, 634 is 1
