Given numbers are 298,930,553,423,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,930,553,423,620 is 21609437220.
Find LCM of 298,930,553,423,620 with Prime Factorization
| 2 | 298, 930, 553, 423, 620 |
| 3 | 149, 465, 553, 423, 310 |
| 5 | 149, 155, 553, 141, 310 |
| 31 | 149, 31, 553, 141, 62 |
| 149, 1, 553, 141, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 149 x 1 x 553 x 141 x 2 = 21609437220
Therefore, the lowest common multiple of 298,930,553,423,620 is 21609437220.
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.
298 x 930 x 553 x 423 x 620 = 40193553229200
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.
298 : 1, 2, 149, 298
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
553 : 1, 7, 79, 553
423 : 1, 3, 9, 47, 141, 423
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,930,553,423,620, is 1.
Now, the common factors can be found like this.
298:2x 149
930:2x 3x 5x 31
553:7x 79
423:3x 3x 47
620:2x 2x 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 2x 3x 5x 31 = 1860
Therefore, the value for common factors is 1860.
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 = 40193553229200/(1x1860)
LCM = 40193553229200/1860
LCM = 21609437220
Thus, we can understand that the LCM of 298,930,553,423,620 is 21609437220.
