To find the GCF of two numbers you first need to work out the prime factors of those numbers. In this case: 30 = 2x3x5 40 = 2x2x2x5 The next step is to identify any common factors. In this case, both numbers have a 2 and a 5 as prime factors. To find the GCF, we simply multiply these numbers together: 2x5 = 10 Thus the GCF of 30 and 40 is 10.
The GCF is 8.
You need at least two numbers to find a GCF.
To find the GCF of 3 numbers you first need to write them as their prime factors: 32 = 2x2x2x2x2 40 = 2x2x2x5 64 = 2x2x2x2x2x2 The next step is to identify any common factors. In this case, all three numbers have three 2s as prime factors. Multiply these together to find the GCF: 2x2x2 = 8 Thus the GCF of 32, 40 and 64 is 8.
The GCF of these numbers is 40.
the answer to GCF of 24 & 40 is 8
You need at least two numbers to find a GCF. If that's 50 and 40, the GCF is 10.
No, 36 and 38 are two numbers between 30 and 40, Their GCF is 2.
21 and 42 have a GCF of 21. 40 and 80 have a GCF of 40. The GCF of 21 and 40 is 1.
To find the GCF, you first need to break the numbers down into their prime factors: 28 = 2x2x7 20 = 2x2x5 40 = 2x2x2x5 The next step is to find any common prime factors. In this case, all three numbers have two 2s as prime factors. Multiply these and you get 4. Therefore the GCF of 28, 20 and 40 is 4.
The GCF is 5.
40 and 98 have no common factors.
