Given numbers are 415, 955, 324, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 955) = 79265
GCD(415, 955) = ( 415 x 955 ) / 79265
= 415 / 955
= 415
Step2:
LCM(5, 324) = 1620
GCD(5, 324) = ( 5 x 324 ) / 1620
= 5 / 324
= 5
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 415, 955, 324, 721 is 1
