GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(554, 648) = 179496
GCD(554, 648) = ( 554 x 648 ) / 179496
= 554 / 648
= 554
Step2:
LCM(2, 970) = 970
GCD(2, 970) = ( 2 x 970 ) / 970
= 2 / 970
= 2
Step3:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
So, Greatest Common Divisor of 554, 648, 970, 639 is 1
