Given numbers are 747,126,742,339
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,126,742,339 is 62632962.
Find LCM of 747,126,742,339 with Prime Factorization
2 | 747, 126, 742, 339 |
3 | 747, 63, 371, 339 |
3 | 249, 21, 371, 113 |
7 | 83, 7, 371, 113 |
83, 1, 53, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 83 x 1 x 53 x 113 = 62632962
Therefore, the lowest common multiple of 747,126,742,339 is 62632962.
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.
747 x 126 x 742 x 339 = 23675259636
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.
747 : 1, 3, 9, 83, 249, 747
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
742 : 1, 2, 7, 14, 53, 106, 371, 742
339 : 1, 3, 113, 339
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,126,742,339, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
126:2x 3x 3x 7
742:2x 7x 53
339:3x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 23675259636/(1x378)
LCM = 23675259636/378
LCM = 62632962
Thus, we can understand that the LCM of 747,126,742,339 is 62632962.
