Given numbers are 381, 570, 988, 622
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 570) = 72390
GCD(381, 570) = ( 381 x 570 ) / 72390
= 381 / 570
= 381
Step2:
LCM(3, 988) = 2964
GCD(3, 988) = ( 3 x 988 ) / 2964
= 3 / 988
= 3
Step3:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
So, Greatest Common Divisor of 381, 570, 988, 622 is 1
