Given numbers are 439, 441, 638, 662
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(439, 441) = 193599
GCD(439, 441) = ( 439 x 441 ) / 193599
= 439 / 441
= 439
Step2:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 439, 441, 638, 662 is 1
