Given numbers are 718,870,812,424,619
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,870,812,424,619 is 286905088680.
Find LCM of 718,870,812,424,619 with Prime Factorization
| 2 | 718, 870, 812, 424, 619 |
| 2 | 359, 435, 406, 212, 619 |
| 29 | 359, 435, 203, 106, 619 |
| 359, 15, 7, 106, 619 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 359 x 15 x 7 x 106 x 619 = 286905088680
Therefore, the lowest common multiple of 718,870,812,424,619 is 286905088680.
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.
718 x 870 x 812 x 424 x 619 = 133123961147520
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.
718 : 1, 2, 359, 718
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
424 : 1, 2, 4, 8, 53, 106, 212, 424
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,870,812,424,619, is 1.
Now, the common factors can be found like this.
718:2x 359
870:2x 3x 5x 29
812:2x 2x 7x 29
424:2x 2x 2x 53
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 2x 2x 2x 29 = 464
Therefore, the value for common factors is 464.
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 = 133123961147520/(1x464)
LCM = 133123961147520/464
LCM = 286905088680
Thus, we can understand that the LCM of 718,870,812,424,619 is 286905088680.
