Given numbers are 817,950,143,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,950,143,440 is 23366200.
Find LCM of 817,950,143,440 with Prime Factorization
| 2 | 817, 950, 143, 440 |
| 5 | 817, 475, 143, 220 |
| 11 | 817, 95, 143, 44 |
| 19 | 817, 95, 13, 4 |
| 43, 5, 13, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 19 x 43 x 5 x 13 x 4 = 23366200
Therefore, the lowest common multiple of 817,950,143,440 is 23366200.
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.
817 x 950 x 143 x 440 = 48835358000
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.
817 : 1, 19, 43, 817
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
143 : 1, 11, 13, 143
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,950,143,440, is 1.
Now, the common factors can be found like this.
817:19x 43
950:2x 5x 5x 19
143:11x 13
440:2x 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 5x 11x 19 = 2090
Therefore, the value for common factors is 2090.
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 = 48835358000/(1x2090)
LCM = 48835358000/2090
LCM = 23366200
Thus, we can understand that the LCM of 817,950,143,440 is 23366200.
