Given numbers are 299,235,490,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,235,490,770 is 75745670.
Find LCM of 299,235,490,770 with Prime Factorization
| 2 | 299, 235, 490, 770 |
| 5 | 299, 235, 245, 385 |
| 7 | 299, 47, 49, 77 |
| 299, 47, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 299 x 47 x 7 x 11 = 75745670
Therefore, the lowest common multiple of 299,235,490,770 is 75745670.
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 235 x 490 x 770 = 26510984500
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
235 : 1, 5, 47, 235
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,235,490,770, is 1.
Now, the common factors can be found like this.
299:13x 23
235:5x 47
490:2x 5x 7x 7
770:2x 5x 7x 11
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 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 26510984500/(1x350)
LCM = 26510984500/350
LCM = 75745670
Thus, we can understand that the LCM of 299,235,490,770 is 75745670.
