Steps to Calculate GCD of 970, 283, 781, 638 using LCM Formula
Given numbers are 970, 283, 781, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 283) = 274510
GCD(970, 283) = ( 970 x 283 ) / 274510
= 970 / 283
= 970
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 970, 283, 781, 638 is 1
