Given numbers are 767,600,638,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 767,600,638,440 is 146803800.
Find LCM of 767,600,638,440 with Prime Factorization
| 2 | 767, 600, 638, 440 |
| 2 | 767, 300, 319, 220 |
| 2 | 767, 150, 319, 110 |
| 5 | 767, 75, 319, 55 |
| 11 | 767, 15, 319, 11 |
| 767, 15, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 767 x 15 x 29 x 1 = 146803800
Therefore, the lowest common multiple of 767,600,638,440 is 146803800.
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.
767 x 600 x 638 x 440 = 129187344000
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.
767 : 1, 13, 59, 767
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
638 : 1, 2, 11, 22, 29, 58, 319, 638
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,600,638,440, is 1.
Now, the common factors can be found like this.
767:13x 59
600:2x 2x 2x 3x 5x 5
638:2x 11x 29
440:2x 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 2x 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 129187344000/(1x880)
LCM = 129187344000/880
LCM = 146803800
Thus, we can understand that the LCM of 767,600,638,440 is 146803800.
