Find LCM of 338,175,748,143,221 with Prime Factorization
2 | 338, 175, 748, 143, 221 |
11 | 169, 175, 374, 143, 221 |
13 | 169, 175, 34, 13, 221 |
17 | 1, 175, 34, 13, 17 |
1, 175, 2, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 17 x 1 x 175 x 2 x 13 x 1 = 22122100
Therefore, the lowest common multiple of 338,175,748,143,221 is 22122100.
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.
338 x 175 x 748 x 143 x 221 = 1398249452600
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.
338 : 1, 2, 13, 26, 169, 338
175 : 1, 5, 7, 25, 35, 175
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
143 : 1, 11, 13, 143
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,175,748,143,221, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
175:5x 5x 7
748:2x 2x 11x 17
143:11x 13
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13x 13x 17 = 63206
Therefore, the value for common factors is 63206.
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 = 1398249452600/(1x63206)
LCM = 1398249452600/63206
LCM = 22122100
Thus, we can understand that the LCM of 338,175,748,143,221 is 22122100.
