Given numbers are 708,547,765,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 708,547,765,840 is 1382575320.
Find LCM of 708,547,765,840 with Prime Factorization
| 2 | 708, 547, 765, 840 |
| 2 | 354, 547, 765, 420 |
| 3 | 177, 547, 765, 210 |
| 5 | 59, 547, 255, 70 |
| 59, 547, 51, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 547 x 51 x 14 = 1382575320
Therefore, the lowest common multiple of 708,547,765,840 is 1382575320.
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.
708 x 547 x 765 x 840 = 248863557600
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
547 : 1, 547
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
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 708,547,765,840, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
547:547
765:3x 3x 5x 17
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 248863557600/(1x180)
LCM = 248863557600/180
LCM = 1382575320
Thus, we can understand that the LCM of 708,547,765,840 is 1382575320.
