Given numbers are 448,426,646,458,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 448,426,646,458,820 is 1446936536640.
Find LCM of 448,426,646,458,820 with Prime Factorization
2 | 448, 426, 646, 458, 820 |
2 | 224, 213, 323, 229, 410 |
112, 213, 323, 229, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 112 x 213 x 323 x 229 x 205 = 1446936536640
Therefore, the lowest common multiple of 448,426,646,458,820 is 1446936536640.
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.
448 x 426 x 646 x 458 x 820 = 46301969172480
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.
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
426 : 1, 2, 3, 6, 71, 142, 213, 426
646 : 1, 2, 17, 19, 34, 38, 323, 646
458 : 1, 2, 229, 458
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,426,646,458,820, is 2.
Now, the common factors can be found like this.
448:2x 2x 2x 2x 2x 2x 7
426:2x 3x 71
646:2x 17x 19
458:2x 229
820:2x 2x 5x 41
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 2 = 16
Therefore, the value for common factors is 16.
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 = 46301969172480/(2x16)
LCM = 46301969172480/32
LCM = 1446936536640
Thus, we can understand that the LCM of 448,426,646,458,820 is 1446936536640.
