The LCM of 149,442,321,833,742 is 54901665546.
Find LCM of 149,442,321,833,742 with Prime Factorization
| 2 | 149, 442, 321, 833, 742 |
| 7 | 149, 221, 321, 833, 371 |
| 17 | 149, 221, 321, 119, 53 |
| 149, 13, 321, 7, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 149 x 13 x 321 x 7 x 53 = 54901665546
Therefore, the lowest common multiple of 149,442,321,833,742 is 54901665546.
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.
149 x 442 x 321 x 833 x 742 = 13066596399948
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.
149 : 1, 149
442 : 1, 2, 13, 17, 26, 34, 221, 442
321 : 1, 3, 107, 321
833 : 1, 7, 17, 49, 119, 833
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,442,321,833,742, is 1.
Now, the common factors can be found like this.
149:149
442:2x 13x 17
321:3x 107
833:7x 7x 17
742:2x 7x 53
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 17 = 238
Therefore, the value for common factors is 238.
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 = 13066596399948/(1x238)
LCM = 13066596399948/238
LCM = 54901665546
Thus, we can understand that the LCM of 149,442,321,833,742 is 54901665546.
