Given numbers are 605, 987, 554, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 987) = 597135
GCD(605, 987) = ( 605 x 987 ) / 597135
= 605 / 987
= 605
Step2:
LCM(1, 554) = 554
GCD(1, 554) = ( 1 x 554 ) / 554
= 1 / 554
= 1
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 605, 987, 554, 456 is 1
