Given numbers are 628,344,386,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,344,386,695 is 7244363080.
Find LCM of 628,344,386,695 with Prime Factorization
| 2 | 628, 344, 386, 695 |
| 2 | 314, 172, 193, 695 |
| 157, 86, 193, 695 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 157 x 86 x 193 x 695 = 7244363080
Therefore, the lowest common multiple of 628,344,386,695 is 7244363080.
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.
628 x 344 x 386 x 695 = 57954904640
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.
628 : 1, 2, 4, 157, 314, 628
344 : 1, 2, 4, 8, 43, 86, 172, 344
386 : 1, 2, 193, 386
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,344,386,695, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
344:2x 2x 2x 43
386:2x 193
695:5x 139
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 2 = 8
Therefore, the value for common factors is 8.
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 = 57954904640/(1x8)
LCM = 57954904640/8
LCM = 7244363080
Thus, we can understand that the LCM of 628,344,386,695 is 7244363080.
