The LCM of 748,918,399,619 is 1662676092.
Find LCM of 748,918,399,619 with Prime Factorization
| 2 | 748, 918, 399, 619 |
| 3 | 374, 459, 399, 619 |
| 17 | 374, 153, 133, 619 |
| 22, 9, 133, 619 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 22 x 9 x 133 x 619 = 1662676092
Therefore, the lowest common multiple of 748,918,399,619 is 1662676092.
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 918 x 399 x 619 = 169592961384
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
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
399 : 1, 3, 7, 19, 21, 57, 133, 399
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,918,399,619, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
918:2x 3x 3x 3x 17
399:3x 7x 19
619:619
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 17 = 102
Therefore, the value for common factors is 102.
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 = 169592961384/(1x102)
LCM = 169592961384/102
LCM = 1662676092
Thus, we can understand that the LCM of 748,918,399,619 is 1662676092.
