Steps to Calculate GCD of 442, 691, 815, 485 using LCM Formula
Given numbers are 442, 691, 815, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(442, 691) = 305422
GCD(442, 691) = ( 442 x 691 ) / 305422
= 442 / 691
= 442
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 442, 691, 815, 485 is 1
