Given numbers are 785,874,356,360,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,874,356,360,638 is 701236122840.
Find LCM of 785,874,356,360,638 with Prime Factorization
| 2 | 785, 874, 356, 360, 638 |
| 2 | 785, 437, 178, 180, 319 |
| 5 | 785, 437, 89, 90, 319 |
| 157, 437, 89, 18, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 157 x 437 x 89 x 18 x 319 = 701236122840
Therefore, the lowest common multiple of 785,874,356,360,638 is 701236122840.
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.
785 x 874 x 356 x 360 x 638 = 56098889827200
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.
785 : 1, 5, 157, 785
874 : 1, 2, 19, 23, 38, 46, 437, 874
356 : 1, 2, 4, 89, 178, 356
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,874,356,360,638, is 1.
Now, the common factors can be found like this.
785:5x 157
874:2x 19x 23
356:2x 2x 89
360:2x 2x 2x 3x 3x 5
638:2x 11x 29
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 5 = 80
Therefore, the value for common factors is 80.
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 = 56098889827200/(1x80)
LCM = 56098889827200/80
LCM = 701236122840
Thus, we can understand that the LCM of 785,874,356,360,638 is 701236122840.
