Given numbers are 123, 156, 128, 837
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 156) = 6396
GCD(123, 156) = ( 123 x 156 ) / 6396
= 123 / 156
= 123
Step2:
LCM(3, 128) = 384
GCD(3, 128) = ( 3 x 128 ) / 384
= 3 / 128
= 3
Step3:
LCM(1, 837) = 837
GCD(1, 837) = ( 1 x 837 ) / 837
= 1 / 837
= 1
So, Greatest Common Divisor of 123, 156, 128, 837 is 1
