Given numbers are 955,842,820,751,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,842,820,751,220 is 544705722220.
Find LCM of 955,842,820,751,220 with Prime Factorization
| 2 | 955, 842, 820, 751, 220 |
| 2 | 955, 421, 410, 751, 110 |
| 5 | 955, 421, 205, 751, 55 |
| 191, 421, 41, 751, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 191 x 421 x 41 x 751 x 11 = 544705722220
Therefore, the lowest common multiple of 955,842,820,751,220 is 544705722220.
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.
955 x 842 x 820 x 751 x 220 = 108941144444000
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.
955 : 1, 5, 191, 955
842 : 1, 2, 421, 842
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
751 : 1, 751
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,842,820,751,220, is 1.
Now, the common factors can be found like this.
955:5x 191
842:2x 421
820:2x 2x 5x 41
751:751
220:2x 2x 5x 11
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 108941144444000/(1x200)
LCM = 108941144444000/200
LCM = 544705722220
Thus, we can understand that the LCM of 955,842,820,751,220 is 544705722220.
