Given numbers are 628,316,912,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,316,912,437 is 260165328.
Find LCM of 628,316,912,437 with Prime Factorization
| 2 | 628, 316, 912, 437 |
| 2 | 314, 158, 456, 437 |
| 19 | 157, 79, 228, 437 |
| 157, 79, 12, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 157 x 79 x 12 x 23 = 260165328
Therefore, the lowest common multiple of 628,316,912,437 is 260165328.
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 316 x 912 x 437 = 79090259712
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
316 : 1, 2, 4, 79, 158, 316
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,316,912,437, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
316:2x 2x 79
912:2x 2x 2x 2x 3x 19
437:19x 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 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 79090259712/(1x304)
LCM = 79090259712/304
LCM = 260165328
Thus, we can understand that the LCM of 628,316,912,437 is 260165328.
