Steps to Calculate GCD of 881, 189, 643, 653 using LCM Formula

Given numbers are 881, 189, 643, 653

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(881, 189) = 166509

GCD(881, 189) = ( 881 x 189 ) / 166509

= 881 / 189

= 881


Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1


Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1
