Given numbers are 140,906,663,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,906,663,748 is 154174020.
Find LCM of 140,906,663,748 with Prime Factorization
2 | 140, 906, 663, 748 |
2 | 70, 453, 663, 374 |
3 | 35, 453, 663, 187 |
17 | 35, 151, 221, 187 |
35, 151, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 35 x 151 x 13 x 11 = 154174020
Therefore, the lowest common multiple of 140,906,663,748 is 154174020.
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.
140 x 906 x 663 x 748 = 62903000160
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
906 : 1, 2, 3, 6, 151, 302, 453, 906
663 : 1, 3, 13, 17, 39, 51, 221, 663
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 140,906,663,748, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
906:2x 3x 151
663:3x 13x 17
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.
2x 2x 2x 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 62903000160/(1x408)
LCM = 62903000160/408
LCM = 154174020
Thus, we can understand that the LCM of 140,906,663,748 is 154174020.
