Given numbers are 556, 450, 580, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 450) = 125100
GCD(556, 450) = ( 556 x 450 ) / 125100
= 556 / 450
= 556
Step2:
LCM(2, 580) = 580
GCD(2, 580) = ( 2 x 580 ) / 580
= 2 / 580
= 2
Step3:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
So, Greatest Common Divisor of 556, 450, 580, 639 is 1
