Given numbers are 914,995,730,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 914,995,730,420 is 2788312380.
Find LCM of 914,995,730,420 with Prime Factorization
| 2 | 914, 995, 730, 420 |
| 5 | 457, 995, 365, 210 |
| 457, 199, 73, 42 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 457 x 199 x 73 x 42 = 2788312380
Therefore, the lowest common multiple of 914,995,730,420 is 2788312380.
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.
914 x 995 x 730 x 420 = 278831238000
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.
914 : 1, 2, 457, 914
995 : 1, 5, 199, 995
730 : 1, 2, 5, 10, 73, 146, 365, 730
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 914,995,730,420, is 1.
Now, the common factors can be found like this.
914:2x 457
995:5x 199
730:2x 5x 73
420:2x 2x 3x 5x 7
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 278831238000/(1x100)
LCM = 278831238000/100
LCM = 2788312380
Thus, we can understand that the LCM of 914,995,730,420 is 2788312380.
