Given numbers are 292,628,158,438,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 292,628,158,438,172 is 467196204.
Find LCM of 292,628,158,438,172 with Prime Factorization
| 2 | 292, 628, 158, 438, 172 |
| 2 | 146, 314, 79, 219, 86 |
| 73 | 73, 157, 79, 219, 43 |
| 1, 157, 79, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 73 x 1 x 157 x 79 x 3 x 43 = 467196204
Therefore, the lowest common multiple of 292,628,158,438,172 is 467196204.
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.
292 x 628 x 158 x 438 x 172 = 2182740665088
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.
292 : 1, 2, 4, 73, 146, 292
628 : 1, 2, 4, 157, 314, 628
158 : 1, 2, 79, 158
438 : 1, 2, 3, 6, 73, 146, 219, 438
172 : 1, 2, 4, 43, 86, 172
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 292,628,158,438,172, is 2.
Now, the common factors can be found like this.
292:2x 2x 73
628:2x 2x 157
158:2x 79
438:2x 3x 73
172:2x 2x 43
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 2x 73 = 2336
Therefore, the value for common factors is 2336.
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 = 2182740665088/(2x2336)
LCM = 2182740665088/4672
LCM = 467196204
Thus, we can understand that the LCM of 292,628,158,438,172 is 467196204.
