Steps to Calculate GCD of 105, 621, 757, 140 using LCM Formula

Given numbers are 105, 621, 757, 140

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

Apply this formula for all numbers.

Step1:

LCM(105, 621) = 21735

GCD(105, 621) = ( 105 x 621 ) / 21735

= 105 / 621

= 105


Step2:

LCM(3, 757) = 2271

GCD(3, 757) = ( 3 x 757 ) / 2271

= 3 / 757

= 3


Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1


So, Greatest Common Divisor of 105, 621, 757, 140 is 1
