Given numbers are 290,129,387,691,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,129,387,691,670 is 5195912310.
Find LCM of 290,129,387,691,670 with Prime Factorization
2 | 290, 129, 387, 691, 670 |
3 | 145, 129, 387, 691, 335 |
5 | 145, 43, 129, 691, 335 |
43 | 29, 43, 129, 691, 67 |
29, 1, 3, 691, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 29 x 1 x 3 x 691 x 67 = 5195912310
Therefore, the lowest common multiple of 290,129,387,691,670 is 5195912310.
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.
290 x 129 x 387 x 691 x 670 = 6702726879900
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
129 : 1, 3, 43, 129
387 : 1, 3, 9, 43, 129, 387
691 : 1, 691
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,129,387,691,670, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
129:3x 43
387:3x 3x 43
691:691
670:2x 5x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 43 = 1290
Therefore, the value for common factors is 1290.
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 = 6702726879900/(1x1290)
LCM = 6702726879900/1290
LCM = 5195912310
Thus, we can understand that the LCM of 290,129,387,691,670 is 5195912310.
