Find LCM of 197,471,572,416,921 with Prime Factorization
2 | 197, 471, 572, 416, 921 |
2 | 197, 471, 286, 208, 921 |
3 | 197, 471, 143, 104, 921 |
13 | 197, 157, 143, 104, 307 |
197, 157, 11, 8, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 197 x 157 x 11 x 8 x 307 = 130350146784
Therefore, the lowest common multiple of 197,471,572,416,921 is 130350146784.
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.
197 x 471 x 572 x 416 x 921 = 20334622898304
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.
197 : 1, 197
471 : 1, 3, 157, 471
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,471,572,416,921, is 1.
Now, the common factors can be found like this.
197:197
471:3x 157
572:2x 2x 11x 13
416:2x 2x 2x 2x 2x 13
921:3x 307
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 20334622898304/(1x156)
LCM = 20334622898304/156
LCM = 130350146784
Thus, we can understand that the LCM of 197,471,572,416,921 is 130350146784.
