Given numbers are 639,679,224,726,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,679,224,726,910 is 109199170080.
Find LCM of 639,679,224,726,910 with Prime Factorization
| 2 | 639, 679, 224, 726, 910 |
| 3 | 639, 679, 112, 363, 455 |
| 7 | 213, 679, 112, 121, 455 |
| 213, 97, 16, 121, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 213 x 97 x 16 x 121 x 65 = 109199170080
Therefore, the lowest common multiple of 639,679,224,726,910 is 109199170080.
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.
639 x 679 x 224 x 726 x 910 = 64209112007040
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.
639 : 1, 3, 9, 71, 213, 639
679 : 1, 7, 97, 679
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,679,224,726,910, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
679:7x 97
224:2x 2x 2x 2x 2x 7
726:2x 3x 11x 11
910:2x 5x 7x 13
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 64209112007040/(1x588)
LCM = 64209112007040/588
LCM = 109199170080
Thus, we can understand that the LCM of 639,679,224,726,910 is 109199170080.
