Given numbers are 648, 831, 556, 470
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 831) = 179496
GCD(648, 831) = ( 648 x 831 ) / 179496
= 648 / 831
= 648
Step2:
LCM(3, 556) = 1668
GCD(3, 556) = ( 3 x 556 ) / 1668
= 3 / 556
= 3
Step3:
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
= 1 / 470
= 1
So, Greatest Common Divisor of 648, 831, 556, 470 is 1
