Given numbers are 748,638,702,329,824
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,638,702,329,824 is 516023916408.
Find LCM of 748,638,702,329,824 with Prime Factorization
| 2 | 748, 638, 702, 329, 824 |
| 2 | 374, 319, 351, 329, 412 |
| 11 | 187, 319, 351, 329, 206 |
| 17, 29, 351, 329, 206 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 29 x 351 x 329 x 206 = 516023916408
Therefore, the lowest common multiple of 748,638,702,329,824 is 516023916408.
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.
748 x 638 x 702 x 329 x 824 = 90820209287808
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
638 : 1, 2, 11, 22, 29, 58, 319, 638
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
329 : 1, 7, 47, 329
824 : 1, 2, 4, 8, 103, 206, 412, 824
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,638,702,329,824, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
638:2x 11x 29
702:2x 3x 3x 3x 13
329:7x 47
824:2x 2x 2x 103
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 90820209287808/(1x176)
LCM = 90820209287808/176
LCM = 516023916408
Thus, we can understand that the LCM of 748,638,702,329,824 is 516023916408.
