Find LCM of 131,456,805,393,428 with Prime Factorization
2 | 131, 456, 805, 393, 428 |
2 | 131, 228, 805, 393, 214 |
3 | 131, 114, 805, 393, 107 |
131 | 131, 38, 805, 131, 107 |
1, 38, 805, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 131 x 1 x 38 x 805 x 1 x 107 = 5145360360
Therefore, the lowest common multiple of 131,456,805,393,428 is 5145360360.
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.
131 x 456 x 805 x 393 x 428 = 8088506485920
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.
131 : 1, 131
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
805 : 1, 5, 7, 23, 35, 115, 161, 805
393 : 1, 3, 131, 393
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,456,805,393,428, is 1.
Now, the common factors can be found like this.
131:131
456:2x 2x 2x 3x 19
805:5x 7x 23
393:3x 131
428:2x 2x 107
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 3x 131 = 1572
Therefore, the value for common factors is 1572.
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 = 8088506485920/(1x1572)
LCM = 8088506485920/1572
LCM = 5145360360
Thus, we can understand that the LCM of 131,456,805,393,428 is 5145360360.
