Given numbers are 931,325,280,782,723
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,325,280,782,723 is 684286675800.
Find LCM of 931,325,280,782,723 with Prime Factorization
| 2 | 931, 325, 280, 782, 723 |
| 5 | 931, 325, 140, 391, 723 |
| 7 | 931, 65, 28, 391, 723 |
| 133, 65, 4, 391, 723 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 133 x 65 x 4 x 391 x 723 = 684286675800
Therefore, the lowest common multiple of 931,325,280,782,723 is 684286675800.
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.
931 x 325 x 280 x 782 x 723 = 47900067306000
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.
931 : 1, 7, 19, 49, 133, 931
325 : 1, 5, 13, 25, 65, 325
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
782 : 1, 2, 17, 23, 34, 46, 391, 782
723 : 1, 3, 241, 723
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,325,280,782,723, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
325:5x 5x 13
280:2x 2x 2x 5x 7
782:2x 17x 23
723:3x 241
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 47900067306000/(1x70)
LCM = 47900067306000/70
LCM = 684286675800
Thus, we can understand that the LCM of 931,325,280,782,723 is 684286675800.
