Steps to Calculate GCD of 571, 562, 28, 139 using LCM Formula

Given numbers are 571, 562, 28, 139

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

Apply this formula for all numbers.

Step1:

LCM(571, 562) = 320902

GCD(571, 562) = ( 571 x 562 ) / 320902

= 571 / 562

= 571


Step2:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1


Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1


So, Greatest Common Divisor of 571, 562, 28, 139 is 1
