Steps to Calculate GCD of 661, 673, 140, 663 using LCM Formula
Given numbers are 661, 673, 140, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 673) = 444853
GCD(661, 673) = ( 661 x 673 ) / 444853
= 661 / 673
= 661
Step2:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 661, 673, 140, 663 is 1
