Given numbers are 587,140,840,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 587,140,840,634 is 156306360.
Find LCM of 587,140,840,634 with Prime Factorization
| 2 | 587, 140, 840, 634 |
| 2 | 587, 70, 420, 317 |
| 5 | 587, 35, 210, 317 |
| 7 | 587, 7, 42, 317 |
| 587, 1, 6, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 587 x 1 x 6 x 317 = 156306360
Therefore, the lowest common multiple of 587,140,840,634 is 156306360.
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.
587 x 140 x 840 x 634 = 43765780800
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.
587 : 1, 587
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
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
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 587,140,840,634, is 1.
Now, the common factors can be found like this.
587:587
140:2x 2x 5x 7
840:2x 2x 2x 3x 5x 7
634:2x 317
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 43765780800/(1x280)
LCM = 43765780800/280
LCM = 156306360
Thus, we can understand that the LCM of 587,140,840,634 is 156306360.
