Given numbers are 724,748,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,748,429 is 5280132.
Find LCM of 724,748,429 with Prime Factorization
| 2 | 724, 748, 429 |
| 2 | 362, 374, 429 |
| 11 | 181, 187, 429 |
| 181, 17, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 181 x 17 x 39 = 5280132
Therefore, the lowest common multiple of 724,748,429 is 5280132.
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.
724 x 748 x 429 = 232325808
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.
724 : 1, 2, 4, 181, 362, 724
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,748,429, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
748:2x 2x 11x 17
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 232325808/(1x44)
LCM = 232325808/44
LCM = 5280132
Thus, we can understand that the LCM of 724,748,429 is 5280132.
