GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 898) = 300830
GCD(670, 898) = ( 670 x 898 ) / 300830
= 670 / 898
= 670
Step2:
LCM(2, 989) = 1978
GCD(2, 989) = ( 2 x 989 ) / 1978
= 2 / 989
= 2
Step3:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
So, Greatest Common Divisor of 670, 898, 989, 308 is 1
