Given numbers are 551,454,639,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,454,639,646 is 2717422902.
Find LCM of 551,454,639,646 with Prime Factorization
2 | 551, 454, 639, 646 |
19 | 551, 227, 639, 323 |
29, 227, 639, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 29 x 227 x 639 x 17 = 2717422902
Therefore, the lowest common multiple of 551,454,639,646 is 2717422902.
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.
551 x 454 x 639 x 646 = 103262070276
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.
551 : 1, 19, 29, 551
454 : 1, 2, 227, 454
639 : 1, 3, 9, 71, 213, 639
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,454,639,646, is 1.
Now, the common factors can be found like this.
551:19x 29
454:2x 227
639:3x 3x 71
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 103262070276/(1x38)
LCM = 103262070276/38
LCM = 2717422902
Thus, we can understand that the LCM of 551,454,639,646 is 2717422902.
