Find LCM of 345,893,782,564 with Prime Factorization
| 2 | 345, 893, 782, 564 |
| 3 | 345, 893, 391, 282 |
| 23 | 115, 893, 391, 94 |
| 47 | 5, 893, 17, 94 |
| 5, 19, 17, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 47 x 5 x 19 x 17 x 2 = 20949780
Therefore, the lowest common multiple of 345,893,782,564 is 20949780.
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.
345 x 893 x 782 x 564 = 135880273080
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
893 : 1, 19, 47, 893
782 : 1, 2, 17, 23, 34, 46, 391, 782
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,893,782,564, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
893:19x 47
782:2x 17x 23
564:2x 2x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23x 47 = 6486
Therefore, the value for common factors is 6486.
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 = 135880273080/(1x6486)
LCM = 135880273080/6486
LCM = 20949780
Thus, we can understand that the LCM of 345,893,782,564 is 20949780.
