GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(446, 427) = 190442
GCD(446, 427) = ( 446 x 427 ) / 190442
= 446 / 427
= 446
Step2:
LCM(1, 424) = 424
GCD(1, 424) = ( 1 x 424 ) / 424
= 1 / 424
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 446, 427, 424, 640 is 1
