Given numbers are 470,561,319,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,561,319,430 is 328796490.
Find LCM of 470,561,319,430 with Prime Factorization
| 2 | 470, 561, 319, 430 |
| 5 | 235, 561, 319, 215 |
| 11 | 47, 561, 319, 43 |
| 47, 51, 29, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 47 x 51 x 29 x 43 = 328796490
Therefore, the lowest common multiple of 470,561,319,430 is 328796490.
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.
470 x 561 x 319 x 430 = 36167613900
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
561 : 1, 3, 11, 17, 33, 51, 187, 561
319 : 1, 11, 29, 319
430 : 1, 2, 5, 10, 43, 86, 215, 430
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,561,319,430, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
561:3x 11x 17
319:11x 29
430:2x 5x 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 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 36167613900/(1x110)
LCM = 36167613900/110
LCM = 328796490
Thus, we can understand that the LCM of 470,561,319,430 is 328796490.
