Steps to Calculate GCD of 695, 645, 309, 655 using LCM Formula
Given numbers are 695, 645, 309, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(695, 645) = 89655
GCD(695, 645) = ( 695 x 645 ) / 89655
= 695 / 645
= 695
Step2:
LCM(5, 309) = 1545
GCD(5, 309) = ( 5 x 309 ) / 1545
= 5 / 309
= 5
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 695, 645, 309, 655 is 1
