Given numbers are 865,174,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,174,748 is 56290740.
Find LCM of 865,174,748 with Prime Factorization
2 | 865, 174, 748 |
865, 87, 374 |
Multiply the prime numbers at the bottom and the left side.
2 x 865 x 87 x 374 = 56290740
Therefore, the lowest common multiple of 865,174,748 is 56290740.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
865 x 174 x 748 = 112581480
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
865 : 1, 5, 173, 865
174 : 1, 2, 3, 6, 29, 58, 87, 174
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,174,748, is 1.
Now, the common factors can be found like this.
865:5x 173
174:2x 3x 29
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 112581480/(1x2)
LCM = 112581480/2
LCM = 56290740
Thus, we can understand that the LCM of 865,174,748 is 56290740.
