The LCM of 920,533,390,391,722 is 9028017960.
Find LCM of 920,533,390,391,722 with Prime Factorization
| 2 | 920, 533, 390, 391, 722 |
| 5 | 460, 533, 195, 391, 361 |
| 13 | 92, 533, 39, 391, 361 |
| 23 | 92, 41, 3, 391, 361 |
| 4, 41, 3, 17, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 23 x 4 x 41 x 3 x 17 x 361 = 9028017960
Therefore, the lowest common multiple of 920,533,390,391,722 is 9028017960.
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.
920 x 533 x 390 x 391 x 722 = 53987547400800
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
533 : 1, 13, 41, 533
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
391 : 1, 17, 23, 391
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,533,390,391,722, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
533:13x 41
390:2x 3x 5x 13
391:17x 23
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 13x 23 = 5980
Therefore, the value for common factors is 5980.
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 = 53987547400800/(1x5980)
LCM = 53987547400800/5980
LCM = 9028017960
Thus, we can understand that the LCM of 920,533,390,391,722 is 9028017960.
