Given numbers are 615, 128, 728, 554
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 128) = 78720
GCD(615, 128) = ( 615 x 128 ) / 78720
= 615 / 128
= 615
Step2:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
Step3:
LCM(1, 554) = 554
GCD(1, 554) = ( 1 x 554 ) / 554
= 1 / 554
= 1
So, Greatest Common Divisor of 615, 128, 728, 554 is 1
