Steps to Calculate GCD of 654, 607, 830, 809 using LCM Formula

Given numbers are 654, 607, 830, 809

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

Apply this formula for all numbers.

Step1:

LCM(654, 607) = 396978

GCD(654, 607) = ( 654 x 607 ) / 396978

= 654 / 607

= 654


Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1


Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1


So, Greatest Common Divisor of 654, 607, 830, 809 is 1
