Given numbers are 671,460,690,770,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,460,690,770,139 is 900978540.
Find LCM of 671,460,690,770,139 with Prime Factorization
| 2 | 671, 460, 690, 770, 139 |
| 5 | 671, 230, 345, 385, 139 |
| 11 | 671, 46, 69, 77, 139 |
| 23 | 61, 46, 69, 7, 139 |
| 61, 2, 3, 7, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 23 x 61 x 2 x 3 x 7 x 139 = 900978540
Therefore, the lowest common multiple of 671,460,690,770,139 is 900978540.
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 460 x 690 x 770 x 139 = 22794757062000
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
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,460,690,770,139, is 1.
Now, the common factors can be found like this.
671:11x 61
460:2x 2x 5x 23
690:2x 3x 5x 23
770:2x 5x 7x 11
139:139
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 5x 5x 11x 23 = 25300
Therefore, the value for common factors is 25300.
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 = 22794757062000/(1x25300)
LCM = 22794757062000/25300
LCM = 900978540
Thus, we can understand that the LCM of 671,460,690,770,139 is 900978540.
