Given numbers are 299,946,980,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,946,980,690 is 415795380.
Find LCM of 299,946,980,690 with Prime Factorization
| 2 | 299, 946, 980, 690 |
| 5 | 299, 473, 490, 345 |
| 23 | 299, 473, 98, 69 |
| 13, 473, 98, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 13 x 473 x 98 x 3 = 415795380
Therefore, the lowest common multiple of 299,946,980,690 is 415795380.
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.
299 x 946 x 980 x 690 = 191265874800
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.
299 : 1, 13, 23, 299
946 : 1, 2, 11, 22, 43, 86, 473, 946
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,946,980,690, is 1.
Now, the common factors can be found like this.
299:13x 23
946:2x 11x 43
980:2x 2x 5x 7x 7
690:2x 3x 5x 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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 191265874800/(1x460)
LCM = 191265874800/460
LCM = 415795380
Thus, we can understand that the LCM of 299,946,980,690 is 415795380.
