GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 609) = 88914
GCD(438, 609) = ( 438 x 609 ) / 88914
= 438 / 609
= 438
Step2:
LCM(3, 813) = 813
GCD(3, 813) = ( 3 x 813 ) / 813
= 3 / 813
= 3
Step3:
LCM(3, 256) = 768
GCD(3, 256) = ( 3 x 256 ) / 768
= 3 / 256
= 3
So, Greatest Common Divisor of 438, 609, 813, 256 is 1
