Given numbers are 681,628,730,590,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,628,730,590,785 is 9209830380.
Find LCM of 681,628,730,590,785 with Prime Factorization
| 2 | 681, 628, 730, 590, 785 |
| 5 | 681, 314, 365, 295, 785 |
| 157 | 681, 314, 73, 59, 157 |
| 681, 2, 73, 59, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 157 x 681 x 2 x 73 x 59 x 1 = 9209830380
Therefore, the lowest common multiple of 681,628,730,590,785 is 9209830380.
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.
681 x 628 x 730 x 590 x 785 = 144594336966000
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.
681 : 1, 3, 227, 681
628 : 1, 2, 4, 157, 314, 628
730 : 1, 2, 5, 10, 73, 146, 365, 730
590 : 1, 2, 5, 10, 59, 118, 295, 590
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,628,730,590,785, is 1.
Now, the common factors can be found like this.
681:3x 227
628:2x 2x 157
730:2x 5x 73
590:2x 5x 59
785:5x 157
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 5x 5x 157 = 15700
Therefore, the value for common factors is 15700.
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 = 144594336966000/(1x15700)
LCM = 144594336966000/15700
LCM = 9209830380
Thus, we can understand that the LCM of 681,628,730,590,785 is 9209830380.
