Given numbers are 551,847,473,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,847,473,788 is 15813561148.
Find LCM of 551,847,473,788 with Prime Factorization
| 11 | 551, 847, 473, 788 |
| 551, 77, 43, 788 |
Multiply the prime numbers at the bottom and the left side.
11 x 551 x 77 x 43 x 788 = 15813561148
Therefore, the lowest common multiple of 551,847,473,788 is 15813561148.
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 847 x 473 x 788 = 173949172628
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
847 : 1, 7, 11, 77, 121, 847
473 : 1, 11, 43, 473
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,847,473,788, is 1.
Now, the common factors can be found like this.
551:19x 29
847:7x 11x 11
473:11x 43
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 173949172628/(1x11)
LCM = 173949172628/11
LCM = 15813561148
Thus, we can understand that the LCM of 551,847,473,788 is 15813561148.
