Since 40 is a factor of 120, all of its factors are common.
The GCF of 40 and 120 is 40.One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.The common factors are 1, 2, 4, 5, 8, 10, 20, and 40. Therefore, the greatest common factor is 40.Since 40 is a factor of 120, it is automatically the GCF.
The common factors are 1, 2 and 4. The LCM is 120.
Since 40 is a factor of 120, all the factors of 40 are common to 120. There can only be one greatest. 1, 2, 4, 5, 8, 10, 20, 40 The GCF is 40.
The GCF is 10.
The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120. For them to be common, they need to be compared to another set of factors.
The common factors are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1, 2, 5 and 10.
1, 2, 4, 5, 8, 10, 20 and 40, the GCF
The Highest Common Factor (HCF) of 120 and 160 is the largest positive integer that divides both 120 and 160 without leaving a remainder. To find the HCF, we need to determine the common factors of 120 and 160. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160. The largest common factor between 120 and 160 is 40. Therefore, the HCF of 120 and 160 is 40.
The least common multiple of 20 , 40 , 30 = 120
The Least Common Multiple (LCM) for 20 40 30 is 120.
