GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 475) = 389025
GCD(819, 475) = ( 819 x 475 ) / 389025
= 819 / 475
= 819
Step2:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 819, 475, 664, 615 is 1
