Given numbers are 665, 130, 61, 298
The list of prime factors of all numbers are
Prime factors of 665 are 5 x 7 x 19
Prime factors of 130 are 2 x 5 x 13
Prime factors of 61 are 61
Prime factors of 298 are 2 x 149
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 665, 130, 61, 298
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 130) = 17290
GCD(665, 130) = ( 665 x 130 ) / 17290
= 665 / 130
= 665
Step2:
LCM(5, 61) = 305
GCD(5, 61) = ( 5 x 61 ) / 305
= 5 / 61
= 5
Step3:
LCM(1, 298) = 298
GCD(1, 298) = ( 1 x 298 ) / 298
= 1 / 298
= 1
So, Greatest Common Divisor of 665, 130, 61, 298 is 1
