Find LCM of 157,747,450,131,768 with Prime Factorization
2 | 157, 747, 450, 131, 768 |
3 | 157, 747, 225, 131, 384 |
3 | 157, 249, 75, 131, 128 |
157, 83, 25, 131, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 157 x 83 x 25 x 131 x 128 = 98326713600
Therefore, the lowest common multiple of 157,747,450,131,768 is 98326713600.
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.
157 x 747 x 450 x 131 x 768 = 5309642534400
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.
157 : 1, 157
747 : 1, 3, 9, 83, 249, 747
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
131 : 1, 131
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,747,450,131,768, is 1.
Now, the common factors can be found like this.
157:157
747:3x 3x 83
450:2x 3x 3x 5x 5
131:131
768:2x 2x 2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 5309642534400/(1x54)
LCM = 5309642534400/54
LCM = 98326713600
Thus, we can understand that the LCM of 157,747,450,131,768 is 98326713600.
