The GCF of 120 and 150 is 30. The GCF can't be greater than the difference between the pair of numbers, which is 30. Since 30 is a factor of both 120 and 150, we know it is the GCF.
The Greatest Common Factor (GCF) of 70 and 150 is: 10
The GCF is 15.
The numbers 150 and 120 can be evenly divided by their greatest common factor, which is 30. This means that both 150 and 120 can be evenly divided by 30 without leaving a remainder. In mathematical terms, 150 ÷ 30 = 5 and 120 ÷ 30 = 4, so 30 goes into 150 and 120 evenly.
There is not a greatest common factor of 150 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150.The prime factors of 150 are 2, 3, 5, and 5.You need at least two numbers to find a GCF.
