Steps to Calculate GCD of 128, 570, 865, 355 using LCM Formula

Given numbers are 128, 570, 865, 355

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

Apply this formula for all numbers.

Step1:

LCM(128, 570) = 36480

GCD(128, 570) = ( 128 x 570 ) / 36480

= 128 / 570

= 128


Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2


Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1


So, Greatest Common Divisor of 128, 570, 865, 355 is 1
