Given numbers are 476,840,617,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,840,617,994 is 625563960.
Find LCM of 476,840,617,994 with Prime Factorization
| 2 | 476, 840, 617, 994 |
| 2 | 238, 420, 617, 497 |
| 7 | 119, 210, 617, 497 |
| 17, 30, 617, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 17 x 30 x 617 x 71 = 625563960
Therefore, the lowest common multiple of 476,840,617,994 is 625563960.
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.
476 x 840 x 617 x 994 = 245221072320
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
617 : 1, 617
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,840,617,994, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
840:2x 2x 2x 3x 5x 7
617:617
994:2x 7x 71
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 245221072320/(1x392)
LCM = 245221072320/392
LCM = 625563960
Thus, we can understand that the LCM of 476,840,617,994 is 625563960.
