Given numbers are 315,737,221,639,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,737,221,639,767 is 214921902195.
Find LCM of 315,737,221,639,767 with Prime Factorization
| 3 | 315, 737, 221, 639, 767 |
| 3 | 105, 737, 221, 213, 767 |
| 13 | 35, 737, 221, 71, 767 |
| 35, 737, 17, 71, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 35 x 737 x 17 x 71 x 59 = 214921902195
Therefore, the lowest common multiple of 315,737,221,639,767 is 214921902195.
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.
315 x 737 x 221 x 639 x 767 = 25145862556815
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
737 : 1, 11, 67, 737
221 : 1, 13, 17, 221
639 : 1, 3, 9, 71, 213, 639
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,737,221,639,767, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
737:11x 67
221:13x 17
639:3x 3x 71
767:13x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 25145862556815/(1x117)
LCM = 25145862556815/117
LCM = 214921902195
Thus, we can understand that the LCM of 315,737,221,639,767 is 214921902195.
