Given numbers are 375,429,616,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 375,429,616,644 is 69069000.
Find LCM of 375,429,616,644 with Prime Factorization
| 2 | 375, 429, 616, 644 |
| 2 | 375, 429, 308, 322 |
| 3 | 375, 429, 154, 161 |
| 7 | 125, 143, 154, 161 |
| 11 | 125, 143, 22, 23 |
| 125, 13, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 125 x 13 x 2 x 23 = 69069000
Therefore, the lowest common multiple of 375,429,616,644 is 69069000.
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.
375 x 429 x 616 x 644 = 63819756000
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.
375 : 1, 3, 5, 15, 25, 75, 125, 375
429 : 1, 3, 11, 13, 33, 39, 143, 429
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 375,429,616,644, is 1.
Now, the common factors can be found like this.
375:3x 5x 5x 5
429:3x 11x 13
616:2x 2x 2x 7x 11
644:2x 2x 7x 23
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 3x 7x 11 = 924
Therefore, the value for common factors is 924.
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 = 63819756000/(1x924)
LCM = 63819756000/924
LCM = 69069000
Thus, we can understand that the LCM of 375,429,616,644 is 69069000.
