Steps to Calculate GCD of 645, 889, 650, 905 using LCM Formula

Given numbers are 645, 889, 650, 905

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

Apply this formula for all numbers.

Step1:

LCM(645, 889) = 573405

GCD(645, 889) = ( 645 x 889 ) / 573405

= 645 / 889

= 645


Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1


Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1


So, Greatest Common Divisor of 645, 889, 650, 905 is 1
