The Greatest Common Divisor (GCD) for 5 7 is 1
The numbers that go into both 28 and 70 are known as their common divisors. The common divisors of 28 are 1, 2, 4, 7, 14, and 28, while the common divisors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common divisors of both numbers are 1, 2, 7, and 14. Hence, the numbers that go into both 28 and 70 are 1, 2, 7, and 14.
The divisors of 35 are: 1, 5, 7, 35.
The common divisors are: 1, 2, 7, 14.
7 has two factors, one and itself. For them to be common, they need to be compared to another set of factors.
2 divisors: 1, 7
The GCF is 7.
The divisors of 4,375 are 1, 5, 7, 25, 35, 125, 175, 625, 875, 4375.
The single-digit divisors of 7,000 are 1, 2, 4, 5, 7, 8.
Since 7 is a prime, its only divisors are 1 and 7.
1, 2, 7, and 14 are common divisors (and common factors) of 28 and 42.
There are 8 divisors of 105 (viz: 1, 3, 5, 7, 15, 21, 35, 105)
0.35 =35/100 but both 35 and 100 are divisible by 5. So 35/5 = 7 and 100/5 =20. Therefore 35/100=7/20. There are no common divisors of 7 and 20, therefore 7/20 is the simplest form.
