GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 472) = 38232
GCD(648, 472) = ( 648 x 472 ) / 38232
= 648 / 472
= 648
Step2:
LCM(8, 779) = 6232
GCD(8, 779) = ( 8 x 779 ) / 6232
= 8 / 779
= 8
Step3:
LCM(1, 748) = 748
GCD(1, 748) = ( 1 x 748 ) / 748
= 1 / 748
= 1
So, Greatest Common Divisor of 648, 472, 779, 748 is 1
