Given numbers are 498, 921, 290, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(498, 921) = 152886
GCD(498, 921) = ( 498 x 921 ) / 152886
= 498 / 921
= 498
Step2:
LCM(3, 290) = 870
GCD(3, 290) = ( 3 x 290 ) / 870
= 3 / 290
= 3
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 498, 921, 290, 649 is 1
