Find LCM of 446,440,860,639,684 with Prime Factorization
| 2 | 446, 440, 860, 639, 684 |
| 2 | 223, 220, 430, 639, 342 |
| 3 | 223, 110, 215, 639, 171 |
| 3 | 223, 110, 215, 213, 57 |
| 5 | 223, 110, 215, 71, 19 |
| 223, 22, 43, 71, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 223 x 22 x 43 x 71 x 19 = 51224821560
Therefore, the lowest common multiple of 446,440,860,639,684 is 51224821560.
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.
446 x 440 x 860 x 639 x 684 = 73763743046400
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.
446 : 1, 2, 223, 446
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
639 : 1, 3, 9, 71, 213, 639
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,440,860,639,684, is 1.
Now, the common factors can be found like this.
446:2x 223
440:2x 2x 2x 5x 11
860:2x 2x 5x 43
639:3x 3x 71
684:2x 2x 3x 3x 19
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 2x 2x 3x 3x 5 = 1440
Therefore, the value for common factors is 1440.
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 = 73763743046400/(1x1440)
LCM = 73763743046400/1440
LCM = 51224821560
Thus, we can understand that the LCM of 446,440,860,639,684 is 51224821560.
