Given numbers are 708,804,896,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 708,804,896,840 is 53128320.
Find LCM of 708,804,896,840 with Prime Factorization
| 2 | 708, 804, 896, 840 |
| 2 | 354, 402, 448, 420 |
| 2 | 177, 201, 224, 210 |
| 3 | 177, 201, 112, 105 |
| 7 | 59, 67, 112, 35 |
| 59, 67, 16, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 59 x 67 x 16 x 5 = 53128320
Therefore, the lowest common multiple of 708,804,896,840 is 53128320.
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 804 x 896 x 840 = 428426772480
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
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
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
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,804,896,840, is 4.
Now, the common factors can be found like this.
708:2x 2x 3x 59
804:2x 2x 3x 67
896:2x 2x 2x 2x 2x 2x 2x 7
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 2x 2x 2x 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 428426772480/(4x2016)
LCM = 428426772480/8064
LCM = 53128320
Thus, we can understand that the LCM of 708,804,896,840 is 53128320.
