Steps to Calculate GCD of 645, 501, 557, 553 using LCM Formula

Given numbers are 645, 501, 557, 553

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

Apply this formula for all numbers.

Step1:

LCM(645, 501) = 107715

GCD(645, 501) = ( 645 x 501 ) / 107715

= 645 / 501

= 645


Step2:

LCM(3, 557) = 1671

GCD(3, 557) = ( 3 x 557 ) / 1671

= 3 / 557

= 3


Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1


So, Greatest Common Divisor of 645, 501, 557, 553 is 1
