Given numbers are 436,489,345,370,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 436,489,345,370,220 is 9979013220.
Find LCM of 436,489,345,370,220 with Prime Factorization
| 2 | 436, 489, 345, 370, 220 |
| 2 | 218, 489, 345, 185, 110 |
| 3 | 109, 489, 345, 185, 55 |
| 5 | 109, 163, 115, 185, 55 |
| 109, 163, 23, 37, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 109 x 163 x 23 x 37 x 11 = 9979013220
Therefore, the lowest common multiple of 436,489,345,370,220 is 9979013220.
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.
436 x 489 x 345 x 370 x 220 = 5987407932000
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.
436 : 1, 2, 4, 109, 218, 436
489 : 1, 3, 163, 489
345 : 1, 3, 5, 15, 23, 69, 115, 345
370 : 1, 2, 5, 10, 37, 74, 185, 370
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,489,345,370,220, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
489:3x 163
345:3x 5x 23
370:2x 5x 37
220:2x 2x 5x 11
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 5987407932000/(1x600)
LCM = 5987407932000/600
LCM = 9979013220
Thus, we can understand that the LCM of 436,489,345,370,220 is 9979013220.
