Given numbers are 169,385,943,971,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,385,943,971,676 is 238307849780.
Find LCM of 169,385,943,971,676 with Prime Factorization
| 13 | 169, 385, 943, 971, 676 |
| 13 | 13, 385, 943, 971, 52 |
| 1, 385, 943, 971, 4 |
Multiply the prime numbers at the bottom and the left side.
13 x 13 x 1 x 385 x 943 x 971 x 4 = 238307849780
Therefore, the lowest common multiple of 169,385,943,971,676 is 238307849780.
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.
169 x 385 x 943 x 971 x 676 = 40274026612820
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.
169 : 1, 13, 169
385 : 1, 5, 7, 11, 35, 55, 77, 385
943 : 1, 23, 41, 943
971 : 1, 971
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,385,943,971,676, is 1.
Now, the common factors can be found like this.
169:13x 13
385:5x 7x 11
943:23x 41
971:971
676:2x 2x 13x 13
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 = 40274026612820/(1x169)
LCM = 40274026612820/169
LCM = 238307849780
Thus, we can understand that the LCM of 169,385,943,971,676 is 238307849780.
