Given numbers are 61, 90, 17, 16
The list of prime factors of all numbers are
Prime factors of 61 are 61
Prime factors of 90 are 2 x 3 x 3 x 5
Prime factors of 17 are 17
Prime factors of 16 are 2 x 2 x 2 x 2
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 61, 90, 17, 16
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(61, 90) = 5490
GCD(61, 90) = ( 61 x 90 ) / 5490
= 61 / 90
= 61
Step2:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
Step3:
LCM(1, 16) = 16
GCD(1, 16) = ( 1 x 16 ) / 16
= 1 / 16
= 1
So, Greatest Common Divisor of 61, 90, 17, 16 is 1
