Given numbers are 638, 964, 869, 611
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 964) = 307516
GCD(638, 964) = ( 638 x 964 ) / 307516
= 638 / 964
= 638
Step2:
LCM(2, 869) = 1738
GCD(2, 869) = ( 2 x 869 ) / 1738
= 2 / 869
= 2
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 638, 964, 869, 611 is 1
