Given numbers are 420,503,835,154,613
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,503,835,154,613 is 237895872060.
Find LCM of 420,503,835,154,613 with Prime Factorization
| 2 | 420, 503, 835, 154, 613 |
| 5 | 210, 503, 835, 77, 613 |
| 7 | 42, 503, 167, 77, 613 |
| 6, 503, 167, 11, 613 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 6 x 503 x 167 x 11 x 613 = 237895872060
Therefore, the lowest common multiple of 420,503,835,154,613 is 237895872060.
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.
420 x 503 x 835 x 154 x 613 = 16652711044200
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
503 : 1, 503
835 : 1, 5, 167, 835
154 : 1, 2, 7, 11, 14, 22, 77, 154
613 : 1, 613
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,503,835,154,613, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
503:503
835:5x 167
154:2x 7x 11
613:613
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 = 16652711044200/(1x70)
LCM = 16652711044200/70
LCM = 237895872060
Thus, we can understand that the LCM of 420,503,835,154,613 is 237895872060.
