Given numbers are 671,440,858,763,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,440,858,763,901 is 719608769880.
Find LCM of 671,440,858,763,901 with Prime Factorization
| 2 | 671, 440, 858, 763, 901 |
| 11 | 671, 220, 429, 763, 901 |
| 61, 20, 39, 763, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 61 x 20 x 39 x 763 x 901 = 719608769880
Therefore, the lowest common multiple of 671,440,858,763,901 is 719608769880.
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.
671 x 440 x 858 x 763 x 901 = 174145322310960
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.
671 : 1, 11, 61, 671
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
763 : 1, 7, 109, 763
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,440,858,763,901, is 1.
Now, the common factors can be found like this.
671:11x 61
440:2x 2x 2x 5x 11
858:2x 3x 11x 13
763:7x 109
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 174145322310960/(1x242)
LCM = 174145322310960/242
LCM = 719608769880
Thus, we can understand that the LCM of 671,440,858,763,901 is 719608769880.
