Given numbers are 478,249,356,267,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,249,356,267,390 is 1377084540.
Find LCM of 478,249,356,267,390 with Prime Factorization
| 2 | 478, 249, 356, 267, 390 |
| 3 | 239, 249, 178, 267, 195 |
| 89 | 239, 83, 178, 89, 65 |
| 239, 83, 2, 1, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 89 x 239 x 83 x 2 x 1 x 65 = 1377084540
Therefore, the lowest common multiple of 478,249,356,267,390 is 1377084540.
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.
478 x 249 x 356 x 267 x 390 = 4412178866160
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.
478 : 1, 2, 239, 478
249 : 1, 3, 83, 249
356 : 1, 2, 4, 89, 178, 356
267 : 1, 3, 89, 267
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,249,356,267,390, is 1.
Now, the common factors can be found like this.
478:2x 239
249:3x 83
356:2x 2x 89
267:3x 89
390:2x 3x 5x 13
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 3x 89 = 3204
Therefore, the value for common factors is 3204.
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 = 4412178866160/(1x3204)
LCM = 4412178866160/3204
LCM = 1377084540
Thus, we can understand that the LCM of 478,249,356,267,390 is 1377084540.
