Given numbers are 721, 161, 370, 622
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 161) = 16583
GCD(721, 161) = ( 721 x 161 ) / 16583
= 721 / 161
= 721
Step2:
LCM(7, 370) = 2590
GCD(7, 370) = ( 7 x 370 ) / 2590
= 7 / 370
= 7
Step3:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
So, Greatest Common Divisor of 721, 161, 370, 622 is 1
