Given numbers are 638, 446, 356, 827
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 446) = 142274
GCD(638, 446) = ( 638 x 446 ) / 142274
= 638 / 446
= 638
Step2:
LCM(2, 356) = 356
GCD(2, 356) = ( 2 x 356 ) / 356
= 2 / 356
= 2
Step3:
LCM(2, 827) = 1654
GCD(2, 827) = ( 2 x 827 ) / 1654
= 2 / 827
= 2
So, Greatest Common Divisor of 638, 446, 356, 827 is 1
