Given numbers are 632,107,620,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 632,107,620,840 is 220116120.
Find LCM of 632,107,620,840 with Prime Factorization
| 2 | 632, 107, 620, 840 |
| 2 | 316, 107, 310, 420 |
| 2 | 158, 107, 155, 210 |
| 5 | 79, 107, 155, 105 |
| 79, 107, 31, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 79 x 107 x 31 x 21 = 220116120
Therefore, the lowest common multiple of 632,107,620,840 is 220116120.
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.
632 x 107 x 620 x 840 = 35218579200
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.
632 : 1, 2, 4, 8, 79, 158, 316, 632
107 : 1, 107
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,107,620,840, is 1.
Now, the common factors can be found like this.
632:2x 2x 2x 79
107:107
620:2x 2x 5x 31
840:2x 2x 2x 3x 5x 7
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 5 = 160
Therefore, the value for common factors is 160.
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 = 35218579200/(1x160)
LCM = 35218579200/160
LCM = 220116120
Thus, we can understand that the LCM of 632,107,620,840 is 220116120.
