Steps to Calculate GCD of 298, 145, 557, 617 using LCM Formula
Given numbers are 298, 145, 557, 617
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(298, 145) = 43210
GCD(298, 145) = ( 298 x 145 ) / 43210
= 298 / 145
= 298
Step2:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
Step3:
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
= 1 / 617
= 1
So, Greatest Common Divisor of 298, 145, 557, 617 is 1
