Given numbers are 591,938,930,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,938,930,490 is 601478430.
Find LCM of 591,938,930,490 with Prime Factorization
| 2 | 591, 938, 930, 490 |
| 3 | 591, 469, 465, 245 |
| 5 | 197, 469, 155, 245 |
| 7 | 197, 469, 31, 49 |
| 197, 67, 31, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 197 x 67 x 31 x 7 = 601478430
Therefore, the lowest common multiple of 591,938,930,490 is 601478430.
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.
591 x 938 x 930 x 490 = 252620940600
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.
591 : 1, 3, 197, 591
938 : 1, 2, 7, 14, 67, 134, 469, 938
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,938,930,490, is 1.
Now, the common factors can be found like this.
591:3x 197
938:2x 7x 67
930:2x 3x 5x 31
490:2x 5x 7x 7
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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 252620940600/(1x420)
LCM = 252620940600/420
LCM = 601478430
Thus, we can understand that the LCM of 591,938,930,490 is 601478430.
