GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 381) = 19812
GCD(156, 381) = ( 156 x 381 ) / 19812
= 156 / 381
= 156
Step2:
LCM(3, 287) = 861
GCD(3, 287) = ( 3 x 287 ) / 861
= 3 / 287
= 3
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 156, 381, 287, 456 is 1
