The LCM of 401,642,620,759,264 is 40382352120.
Find LCM of 401,642,620,759,264 with Prime Factorization
| 2 | 401, 642, 620, 759, 264 |
| 2 | 401, 321, 310, 759, 132 |
| 3 | 401, 321, 155, 759, 66 |
| 11 | 401, 107, 155, 253, 22 |
| 401, 107, 155, 23, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 401 x 107 x 155 x 23 x 2 = 40382352120
Therefore, the lowest common multiple of 401,642,620,759,264 is 40382352120.
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.
401 x 642 x 620 x 759 x 264 = 31982822879040
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.
401 : 1, 401
642 : 1, 2, 3, 6, 107, 214, 321, 642
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
759 : 1, 3, 11, 23, 33, 69, 253, 759
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,642,620,759,264, is 1.
Now, the common factors can be found like this.
401:401
642:2x 3x 107
620:2x 2x 5x 31
759:3x 11x 23
264:2x 2x 2x 3x 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 2x 2x 3x 3x 11 = 792
Therefore, the value for common factors is 792.
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 = 31982822879040/(1x792)
LCM = 31982822879040/792
LCM = 40382352120
Thus, we can understand that the LCM of 401,642,620,759,264 is 40382352120.
