Steps to Calculate GCD of 787, 665, 615, 485 using LCM Formula
Given numbers are 787, 665, 615, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 665) = 523355
GCD(787, 665) = ( 787 x 665 ) / 523355
= 787 / 665
= 787
Step2:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 787, 665, 615, 485 is 1
