Given numbers are 708,570,646,829
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 708,570,646,829 is 947895180.
Find LCM of 708,570,646,829 with Prime Factorization
| 2 | 708, 570, 646, 829 |
| 3 | 354, 285, 323, 829 |
| 19 | 118, 95, 323, 829 |
| 118, 5, 17, 829 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 118 x 5 x 17 x 829 = 947895180
Therefore, the lowest common multiple of 708,570,646,829 is 947895180.
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 570 x 646 x 829 = 216120101040
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
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
646 : 1, 2, 17, 19, 34, 38, 323, 646
829 : 1, 829
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,570,646,829, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
570:2x 3x 5x 19
646:2x 17x 19
829:829
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 19 = 228
Therefore, the value for common factors is 228.
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 = 216120101040/(1x228)
LCM = 216120101040/228
LCM = 947895180
Thus, we can understand that the LCM of 708,570,646,829 is 947895180.
