Given numbers are 630,916,616,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,916,616,815 is 1034704440.
Find LCM of 630,916,616,815 with Prime Factorization
| 2 | 630, 916, 616, 815 |
| 2 | 315, 458, 308, 815 |
| 5 | 315, 229, 154, 815 |
| 7 | 63, 229, 154, 163 |
| 9, 229, 22, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 9 x 229 x 22 x 163 = 1034704440
Therefore, the lowest common multiple of 630,916,616,815 is 1034704440.
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.
630 x 916 x 616 x 815 = 289717243200
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
916 : 1, 2, 4, 229, 458, 916
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,916,616,815, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
916:2x 2x 229
616:2x 2x 2x 7x 11
815:5x 163
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 289717243200/(1x280)
LCM = 289717243200/280
LCM = 1034704440
Thus, we can understand that the LCM of 630,916,616,815 is 1034704440.
