Given numbers are 357,169,155,300
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,169,155,300 is 187032300.
Find LCM of 357,169,155,300 with Prime Factorization
| 3 | 357, 169, 155, 300 |
| 5 | 119, 169, 155, 100 |
| 119, 169, 31, 20 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 119 x 169 x 31 x 20 = 187032300
Therefore, the lowest common multiple of 357,169,155,300 is 187032300.
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.
357 x 169 x 155 x 300 = 2805484500
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
169 : 1, 13, 169
155 : 1, 5, 31, 155
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,169,155,300, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
169:13x 13
155:5x 31
300:2x 2x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 2805484500/(1x15)
LCM = 2805484500/15
LCM = 187032300
Thus, we can understand that the LCM of 357,169,155,300 is 187032300.
