Given numbers are 213,316,628,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,316,628,155 is 1637940180.
Find LCM of 213,316,628,155 with Prime Factorization
| 2 | 213, 316, 628, 155 |
| 2 | 213, 158, 314, 155 |
| 213, 79, 157, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 213 x 79 x 157 x 155 = 1637940180
Therefore, the lowest common multiple of 213,316,628,155 is 1637940180.
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.
213 x 316 x 628 x 155 = 6551760720
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.
213 : 1, 3, 71, 213
316 : 1, 2, 4, 79, 158, 316
628 : 1, 2, 4, 157, 314, 628
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,316,628,155, is 1.
Now, the common factors can be found like this.
213:3x 71
316:2x 2x 79
628:2x 2x 157
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 6551760720/(1x4)
LCM = 6551760720/4
LCM = 1637940180
Thus, we can understand that the LCM of 213,316,628,155 is 1637940180.
