Given numbers are 336,980,186,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 336,980,186,391 is 142542960.
Find LCM of 336,980,186,391 with Prime Factorization
| 2 | 336, 980, 186, 391 |
| 2 | 168, 490, 93, 391 |
| 3 | 84, 245, 93, 391 |
| 7 | 28, 245, 31, 391 |
| 4, 35, 31, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 4 x 35 x 31 x 391 = 142542960
Therefore, the lowest common multiple of 336,980,186,391 is 142542960.
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.
336 x 980 x 186 x 391 = 23947217280
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.
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
186 : 1, 2, 3, 6, 31, 62, 93, 186
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 336,980,186,391, is 1.
Now, the common factors can be found like this.
336:2x 2x 2x 2x 3x 7
980:2x 2x 5x 7x 7
186:2x 3x 31
391:17x 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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 23947217280/(1x168)
LCM = 23947217280/168
LCM = 142542960
Thus, we can understand that the LCM of 336,980,186,391 is 142542960.
