Given numbers are 367,478,631,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 367,478,631,390 is 21585292170.
Find LCM of 367,478,631,390 with Prime Factorization
| 2 | 367, 478, 631, 390 |
| 367, 239, 631, 195 |
Multiply the prime numbers at the bottom and the left side.
2 x 367 x 239 x 631 x 195 = 21585292170
Therefore, the lowest common multiple of 367,478,631,390 is 21585292170.
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.
367 x 478 x 631 x 390 = 43170584340
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.
367 : 1, 367
478 : 1, 2, 239, 478
631 : 1, 631
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 367,478,631,390, is 1.
Now, the common factors can be found like this.
367:367
478:2x 239
631:631
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 43170584340/(1x2)
LCM = 43170584340/2
LCM = 21585292170
Thus, we can understand that the LCM of 367,478,631,390 is 21585292170.
