Given numbers are 35, 74, 28, 78
The list of prime factors of all numbers are
Prime factors of 35 are 5 x 7
Prime factors of 74 are 2 x 37
Prime factors of 28 are 2 x 2 x 7
Prime factors of 78 are 2 x 3 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 35, 74, 28, 78
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(35, 74) = 2590
GCD(35, 74) = ( 35 x 74 ) / 2590
= 35 / 74
= 35
Step2:
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
= 1 / 28
= 1
Step3:
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
= 1 / 78
= 1
So, Greatest Common Divisor of 35, 74, 28, 78 is 1
