Steps to Calculate GCD of 861, 187, 618, 663 using LCM Formula

Given numbers are 861, 187, 618, 663

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

Apply this formula for all numbers.

Step1:

LCM(861, 187) = 161007

GCD(861, 187) = ( 861 x 187 ) / 161007

= 861 / 187

= 861


Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1


Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1


So, Greatest Common Divisor of 861, 187, 618, 663 is 1
