Given numbers are 947,637,646,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,637,646,551 is 11301079426.
Find LCM of 947,637,646,551 with Prime Factorization
19 | 947, 637, 646, 551 |
947, 637, 34, 29 |
Multiply the prime numbers at the bottom and the left side.
19 x 947 x 637 x 34 x 29 = 11301079426
Therefore, the lowest common multiple of 947,637,646,551 is 11301079426.
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.
947 x 637 x 646 x 551 = 214720509094
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.
947 : 1, 947
637 : 1, 7, 13, 49, 91, 637
646 : 1, 2, 17, 19, 34, 38, 323, 646
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,637,646,551, is 1.
Now, the common factors can be found like this.
947:947
637:7x 7x 13
646:2x 17x 19
551:19x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 214720509094/(1x19)
LCM = 214720509094/19
LCM = 11301079426
Thus, we can understand that the LCM of 947,637,646,551 is 11301079426.
