The LCM of 748,749,115,859,690 is 166033481460.
Find LCM of 748,749,115,859,690 with Prime Factorization
| 2 | 748, 749, 115, 859, 690 |
| 5 | 374, 749, 115, 859, 345 |
| 23 | 374, 749, 23, 859, 69 |
| 374, 749, 1, 859, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 374 x 749 x 1 x 859 x 3 = 166033481460
Therefore, the lowest common multiple of 748,749,115,859,690 is 166033481460.
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 749 x 115 x 859 x 690 = 38187700735800
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
749 : 1, 7, 107, 749
115 : 1, 5, 23, 115
859 : 1, 859
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,749,115,859,690, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
749:7x 107
115:5x 23
859:859
690:2x 3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 23 = 230
Therefore, the value for common factors is 230.
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 = 38187700735800/(1x230)
LCM = 38187700735800/230
LCM = 166033481460
Thus, we can understand that the LCM of 748,749,115,859,690 is 166033481460.
