Given numbers are 474, 212, 23, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(474, 212) = 50244
GCD(474, 212) = ( 474 x 212 ) / 50244
= 474 / 212
= 474
Step2:
LCM(2, 23) = 46
GCD(2, 23) = ( 2 x 23 ) / 46
= 2 / 23
= 2
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 474, 212, 23, 721 is 1
