Given numbers are 338,320,630,805,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,320,630,805,748 is 14653679040.
Find LCM of 338,320,630,805,748 with Prime Factorization
| 2 | 338, 320, 630, 805, 748 |
| 2 | 169, 160, 315, 805, 374 |
| 5 | 169, 80, 315, 805, 187 |
| 7 | 169, 16, 63, 161, 187 |
| 169, 16, 9, 23, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 169 x 16 x 9 x 23 x 187 = 14653679040
Therefore, the lowest common multiple of 338,320,630,805,748 is 14653679040.
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.
338 x 320 x 630 x 805 x 748 = 41030301312000
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.
338 : 1, 2, 13, 26, 169, 338
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
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
805 : 1, 5, 7, 23, 35, 115, 161, 805
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,320,630,805,748, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
320:2x 2x 2x 2x 2x 2x 5
630:2x 3x 3x 5x 7
805:5x 7x 23
748:2x 2x 11x 17
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 2x 2x 5x 5x 7 = 2800
Therefore, the value for common factors is 2800.
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 = 41030301312000/(1x2800)
LCM = 41030301312000/2800
LCM = 14653679040
Thus, we can understand that the LCM of 338,320,630,805,748 is 14653679040.
