Given numbers are 970, 394, 158, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 394) = 191090
GCD(970, 394) = ( 970 x 394 ) / 191090
= 970 / 394
= 970
Step2:
LCM(2, 158) = 158
GCD(2, 158) = ( 2 x 158 ) / 158
= 2 / 158
= 2
Step3:
LCM(2, 989) = 1978
GCD(2, 989) = ( 2 x 989 ) / 1978
= 2 / 989
= 2
So, Greatest Common Divisor of 970, 394, 158, 989 is 1
