Given numbers are 156, 296, 649, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 296) = 11544
GCD(156, 296) = ( 156 x 296 ) / 11544
= 156 / 296
= 156
Step2:
LCM(4, 649) = 2596
GCD(4, 649) = ( 4 x 649 ) / 2596
= 4 / 649
= 4
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 156, 296, 649, 321 is 1
