Given numbers are 639,478,362,537,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,478,362,537,521 is 5155824001518.
Find LCM of 639,478,362,537,521 with Prime Factorization
| 2 | 639, 478, 362, 537, 521 |
| 3 | 639, 239, 181, 537, 521 |
| 213, 239, 181, 179, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 213 x 239 x 181 x 179 x 521 = 5155824001518
Therefore, the lowest common multiple of 639,478,362,537,521 is 5155824001518.
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.
639 x 478 x 362 x 537 x 521 = 30934944009108
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.
639 : 1, 3, 9, 71, 213, 639
478 : 1, 2, 239, 478
362 : 1, 2, 181, 362
537 : 1, 3, 179, 537
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,478,362,537,521, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
478:2x 239
362:2x 181
537:3x 179
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 30934944009108/(1x6)
LCM = 30934944009108/6
LCM = 5155824001518
Thus, we can understand that the LCM of 639,478,362,537,521 is 5155824001518.
