Steps to Calculate GCD of 780, 772, 839, 121 using LCM Formula

Given numbers are 780, 772, 839, 121

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

Apply this formula for all numbers.

Step1:

LCM(780, 772) = 150540

GCD(780, 772) = ( 780 x 772 ) / 150540

= 780 / 772

= 780


Step2:

LCM(4, 839) = 3356

GCD(4, 839) = ( 4 x 839 ) / 3356

= 4 / 839

= 4


Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1


So, Greatest Common Divisor of 780, 772, 839, 121 is 1
