Given numbers are 578,630,721,294
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,630,721,294 is 131272470.
Find LCM of 578,630,721,294 with Prime Factorization
2 | 578, 630, 721, 294 |
3 | 289, 315, 721, 147 |
7 | 289, 105, 721, 49 |
289, 15, 103, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 289 x 15 x 103 x 7 = 131272470
Therefore, the lowest common multiple of 578,630,721,294 is 131272470.
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.
578 x 630 x 721 x 294 = 77188212360
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.
578 : 1, 2, 17, 34, 289, 578
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
721 : 1, 7, 103, 721
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,630,721,294, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
630:2x 3x 3x 5x 7
721:7x 103
294:2x 3x 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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 77188212360/(1x588)
LCM = 77188212360/588
LCM = 131272470
Thus, we can understand that the LCM of 578,630,721,294 is 131272470.
