Given numbers are 780,725,987,563,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,725,987,563,423 is 62847521100.
Find LCM of 780,725,987,563,423 with Prime Factorization
| 3 | 780, 725, 987, 563, 423 |
| 5 | 260, 725, 329, 563, 141 |
| 47 | 52, 145, 329, 563, 141 |
| 52, 145, 7, 563, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 47 x 52 x 145 x 7 x 563 x 3 = 62847521100
Therefore, the lowest common multiple of 780,725,987,563,423 is 62847521100.
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.
780 x 725 x 987 x 563 x 423 = 132922507126500
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
725 : 1, 5, 25, 29, 145, 725
987 : 1, 3, 7, 21, 47, 141, 329, 987
563 : 1, 563
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,725,987,563,423, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
725:5x 5x 29
987:3x 7x 47
563:563
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 47 = 2115
Therefore, the value for common factors is 2115.
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 = 132922507126500/(1x2115)
LCM = 132922507126500/2115
LCM = 62847521100
Thus, we can understand that the LCM of 780,725,987,563,423 is 62847521100.
