Given numbers are 74, 30, 35, 68
The list of prime factors of all numbers are
Prime factors of 74 are 2 x 37
Prime factors of 30 are 2 x 3 x 5
Prime factors of 35 are 5 x 7
Prime factors of 68 are 2 x 2 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 74, 30, 35, 68
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(74, 30) = 1110
GCD(74, 30) = ( 74 x 30 ) / 1110
= 74 / 30
= 74
Step2:
LCM(2, 35) = 70
GCD(2, 35) = ( 2 x 35 ) / 70
= 2 / 35
= 2
Step3:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
So, Greatest Common Divisor of 74, 30, 35, 68 is 1
