Find LCM of 518,119,221,371,644 with Prime Factorization
2 | 518, 119, 221, 371, 644 |
7 | 259, 119, 221, 371, 322 |
17 | 37, 17, 221, 53, 46 |
37, 1, 13, 53, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 37 x 1 x 13 x 53 x 46 = 279097364
Therefore, the lowest common multiple of 518,119,221,371,644 is 279097364.
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.
518 x 119 x 221 x 371 x 644 = 3254833458968
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
119 : 1, 7, 17, 119
221 : 1, 13, 17, 221
371 : 1, 7, 53, 371
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,119,221,371,644, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
119:7x 17
221:13x 17
371:7x 53
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 7x 17 = 11662
Therefore, the value for common factors is 11662.
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 = 3254833458968/(1x11662)
LCM = 3254833458968/11662
LCM = 279097364
Thus, we can understand that the LCM of 518,119,221,371,644 is 279097364.
