Steps to Calculate GCD of 770, 802, 121, 397 using LCM Formula

Given numbers are 770, 802, 121, 397

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

Apply this formula for all numbers.

Step1:

LCM(770, 802) = 308770

GCD(770, 802) = ( 770 x 802 ) / 308770

= 770 / 802

= 770


Step2:

LCM(2, 121) = 242

GCD(2, 121) = ( 2 x 121 ) / 242

= 2 / 121

= 2


Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1


So, Greatest Common Divisor of 770, 802, 121, 397 is 1
