Steps to Calculate GCD of 861, 575, 695, 728 using LCM Formula

Given numbers are 861, 575, 695, 728

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

Apply this formula for all numbers.

Step1:

LCM(861, 575) = 495075

GCD(861, 575) = ( 861 x 575 ) / 495075

= 861 / 575

= 861


Step2:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1


Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1


So, Greatest Common Divisor of 861, 575, 695, 728 is 1
