Given numbers are 742,942,371,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,942,371,457 is 159713274.
Find LCM of 742,942,371,457 with Prime Factorization
| 2 | 742, 942, 371, 457 |
| 7 | 371, 471, 371, 457 |
| 53 | 53, 471, 53, 457 |
| 1, 471, 1, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 53 x 1 x 471 x 1 x 457 = 159713274
Therefore, the lowest common multiple of 742,942,371,457 is 159713274.
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.
742 x 942 x 371 x 457 = 118507249308
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
942 : 1, 2, 3, 6, 157, 314, 471, 942
371 : 1, 7, 53, 371
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,942,371,457, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
942:2x 3x 157
371:7x 53
457:457
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 53 = 742
Therefore, the value for common factors is 742.
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 = 118507249308/(1x742)
LCM = 118507249308/742
LCM = 159713274
Thus, we can understand that the LCM of 742,942,371,457 is 159713274.
