Find LCM of 221,971,476,572,950 with Prime Factorization
| 2 | 221, 971, 476, 572, 950 |
| 2 | 221, 971, 238, 286, 475 |
| 13 | 221, 971, 119, 143, 475 |
| 17 | 17, 971, 119, 11, 475 |
| 1, 971, 7, 11, 475 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 1 x 971 x 7 x 11 x 475 = 31394663300
Therefore, the lowest common multiple of 221,971,476,572,950 is 31394663300.
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.
221 x 971 x 476 x 572 x 950 = 55505764714400
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.
221 : 1, 13, 17, 221
971 : 1, 971
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,971,476,572,950, is 1.
Now, the common factors can be found like this.
221:13x 17
971:971
476:2x 2x 7x 17
572:2x 2x 11x 13
950:2x 5x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 13x 17 = 1768
Therefore, the value for common factors is 1768.
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 = 55505764714400/(1x1768)
LCM = 55505764714400/1768
LCM = 31394663300
Thus, we can understand that the LCM of 221,971,476,572,950 is 31394663300.
