Given numbers are 436, 556, 605, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 556) = 60604
GCD(436, 556) = ( 436 x 556 ) / 60604
= 436 / 556
= 436
Step2:
LCM(4, 605) = 2420
GCD(4, 605) = ( 4 x 605 ) / 2420
= 4 / 605
= 4
Step3:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
So, Greatest Common Divisor of 436, 556, 605, 397 is 1
