Given numbers are 245, 277, 128, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 277) = 67865
GCD(245, 277) = ( 245 x 277 ) / 67865
= 245 / 277
= 245
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 245, 277, 128, 664 is 1
