Given numbers are 140, 145, 456, 989
The list of prime factors of all numbers are
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 145 are 5 x 29
Prime factors of 456 are 2 x 2 x 2 x 3 x 19
Prime factors of 989 are 23 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 140, 145, 456, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 145) = 4060
GCD(140, 145) = ( 140 x 145 ) / 4060
= 140 / 145
= 140
Step2:
LCM(5, 456) = 2280
GCD(5, 456) = ( 5 x 456 ) / 2280
= 5 / 456
= 5
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 140, 145, 456, 989 is 1
