Steps to Calculate GCD of 444, 578, 221, 767 using LCM Formula
Given numbers are 444, 578, 221, 767
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(444, 578) = 128316
GCD(444, 578) = ( 444 x 578 ) / 128316
= 444 / 578
= 444
Step2:
LCM(2, 221) = 442
GCD(2, 221) = ( 2 x 221 ) / 442
= 2 / 221
= 2
Step3:
LCM(1, 767) = 767
GCD(1, 767) = ( 1 x 767 ) / 767
= 1 / 767
= 1
So, Greatest Common Divisor of 444, 578, 221, 767 is 1
