Given numbers are 320, 778, 622, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(320, 778) = 124480
GCD(320, 778) = ( 320 x 778 ) / 124480
= 320 / 778
= 320
Step2:
LCM(2, 622) = 622
GCD(2, 622) = ( 2 x 622 ) / 622
= 2 / 622
= 2
Step3:
LCM(2, 989) = 1978
GCD(2, 989) = ( 2 x 989 ) / 1978
= 2 / 989
= 2
So, Greatest Common Divisor of 320, 778, 622, 989 is 1
