Given numbers are 817,343,663,676,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,343,663,676,871 is 647303345052.
Find LCM of 817,343,663,676,871 with Prime Factorization
13 | 817, 343, 663, 676, 871 |
817, 343, 51, 52, 67 |
Multiply the prime numbers at the bottom and the left side.
13 x 817 x 343 x 51 x 52 x 67 = 647303345052
Therefore, the lowest common multiple of 817,343,663,676,871 is 647303345052.
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.
817 x 343 x 663 x 676 x 871 = 109394265313788
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.
817 : 1, 19, 43, 817
343 : 1, 7, 49, 343
663 : 1, 3, 13, 17, 39, 51, 221, 663
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,343,663,676,871, is 1.
Now, the common factors can be found like this.
817:19x 43
343:7x 7x 7
663:3x 13x 17
676:2x 2x 13x 13
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 109394265313788/(1x169)
LCM = 109394265313788/169
LCM = 647303345052
Thus, we can understand that the LCM of 817,343,663,676,871 is 647303345052.
