Given numbers are 389,247,572,553,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,247,572,553,242 is 25716807116.
Find LCM of 389,247,572,553,242 with Prime Factorization
| 2 | 389, 247, 572, 553, 242 |
| 11 | 389, 247, 286, 553, 121 |
| 13 | 389, 247, 26, 553, 11 |
| 389, 19, 2, 553, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 389 x 19 x 2 x 553 x 11 = 25716807116
Therefore, the lowest common multiple of 389,247,572,553,242 is 25716807116.
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.
389 x 247 x 572 x 553 x 242 = 7355006835176
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.
389 : 1, 389
247 : 1, 13, 19, 247
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
553 : 1, 7, 79, 553
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,247,572,553,242, is 1.
Now, the common factors can be found like this.
389:389
247:13x 19
572:2x 2x 11x 13
553:7x 79
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 7355006835176/(1x286)
LCM = 7355006835176/286
LCM = 25716807116
Thus, we can understand that the LCM of 389,247,572,553,242 is 25716807116.
