Given numbers are 615, 411, 637, 555
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 411) = 84255
GCD(615, 411) = ( 615 x 411 ) / 84255
= 615 / 411
= 615
Step2:
LCM(3, 637) = 1911
GCD(3, 637) = ( 3 x 637 ) / 1911
= 3 / 637
= 3
Step3:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
So, Greatest Common Divisor of 615, 411, 637, 555 is 1
