Given numbers are 253,790,294,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,790,294,689 is 20243433210.
Find LCM of 253,790,294,689 with Prime Factorization
| 2 | 253, 790, 294, 689 |
| 253, 395, 147, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 253 x 395 x 147 x 689 = 20243433210
Therefore, the lowest common multiple of 253,790,294,689 is 20243433210.
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 790 x 294 x 689 = 40486866420
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
790 : 1, 2, 5, 10, 79, 158, 395, 790
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,790,294,689, is 1.
Now, the common factors can be found like this.
253:11x 23
790:2x 5x 79
294:2x 3x 7x 7
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 40486866420/(1x2)
LCM = 40486866420/2
LCM = 20243433210
Thus, we can understand that the LCM of 253,790,294,689 is 20243433210.
