Given numbers are 175,390,523,721,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 175,390,523,721,830 is 61030883550.
Find LCM of 175,390,523,721,830 with Prime Factorization
| 2 | 175, 390, 523, 721, 830 |
| 5 | 175, 195, 523, 721, 415 |
| 7 | 35, 39, 523, 721, 83 |
| 5, 39, 523, 103, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 5 x 39 x 523 x 103 x 83 = 61030883550
Therefore, the lowest common multiple of 175,390,523,721,830 is 61030883550.
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.
175 x 390 x 523 x 721 x 830 = 21360809242500
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.
175 : 1, 5, 7, 25, 35, 175
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
523 : 1, 523
721 : 1, 7, 103, 721
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 175,390,523,721,830, is 1.
Now, the common factors can be found like this.
175:5x 5x 7
390:2x 3x 5x 13
523:523
721:7x 103
830:2x 5x 83
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 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 21360809242500/(1x350)
LCM = 21360809242500/350
LCM = 61030883550
Thus, we can understand that the LCM of 175,390,523,721,830 is 61030883550.
