Find LCM of 253,493,441,735,521 with Prime Factorization
| 3 | 253, 493, 441, 735, 521 |
| 7 | 253, 493, 147, 245, 521 |
| 7 | 253, 493, 21, 35, 521 |
| 253, 493, 3, 5, 521 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 7 x 253 x 493 x 3 x 5 x 521 = 143289298845
Therefore, the lowest common multiple of 253,493,441,735,521 is 143289298845.
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.
253 x 493 x 441 x 735 x 521 = 21063526930215
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.
253 : 1, 11, 23, 253
493 : 1, 17, 29, 493
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,493,441,735,521, is 1.
Now, the common factors can be found like this.
253:11x 23
493:17x 29
441:3x 3x 7x 7
735:3x 5x 7x 7
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 21063526930215/(1x147)
LCM = 21063526930215/147
LCM = 143289298845
Thus, we can understand that the LCM of 253,493,441,735,521 is 143289298845.
