Given numbers are 551,645,361,812,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,645,361,812,707 is 19096084140.
Find LCM of 551,645,361,812,707 with Prime Factorization
| 7 | 551, 645, 361, 812, 707 |
| 19 | 551, 645, 361, 116, 101 |
| 29 | 29, 645, 19, 116, 101 |
| 1, 645, 19, 4, 101 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 29 x 1 x 645 x 19 x 4 x 101 = 19096084140
Therefore, the lowest common multiple of 551,645,361,812,707 is 19096084140.
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.
551 x 645 x 361 x 812 x 707 = 73653596527980
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.
551 : 1, 19, 29, 551
645 : 1, 3, 5, 15, 43, 129, 215, 645
361 : 1, 19, 361
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,645,361,812,707, is 1.
Now, the common factors can be found like this.
551:19x 29
645:3x 5x 43
361:19x 19
812:2x 2x 7x 29
707:7x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19x 29 = 3857
Therefore, the value for common factors is 3857.
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 = 73653596527980/(1x3857)
LCM = 73653596527980/3857
LCM = 19096084140
Thus, we can understand that the LCM of 551,645,361,812,707 is 19096084140.
