GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 928) = 186528
GCD(402, 928) = ( 402 x 928 ) / 186528
= 402 / 928
= 402
Step2:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 402, 928, 639, 580 is 1
