Steps to Calculate GCD of 695, 420, 12, 955 using LCM Formula

Given numbers are 695, 420, 12, 955

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

Apply this formula for all numbers.

Step1:

LCM(695, 420) = 58380

GCD(695, 420) = ( 695 x 420 ) / 58380

= 695 / 420

= 695


Step2:

LCM(5, 12) = 60

GCD(5, 12) = ( 5 x 12 ) / 60

= 5 / 12

= 5


Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1


So, Greatest Common Divisor of 695, 420, 12, 955 is 1
