Given numbers are 251, 245, 812, 622
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 245) = 61495
GCD(251, 245) = ( 251 x 245 ) / 61495
= 251 / 245
= 251
Step2:
LCM(1, 812) = 812
GCD(1, 812) = ( 1 x 812 ) / 812
= 1 / 812
= 1
Step3:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
So, Greatest Common Divisor of 251, 245, 812, 622 is 1
