Given numbers are 748,371,145,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,371,145,689 is 523102580.
Find LCM of 748,371,145,689 with Prime Factorization
53 | 748, 371, 145, 689 |
748, 7, 145, 13 |
Multiply the prime numbers at the bottom and the left side.
53 x 748 x 7 x 145 x 13 = 523102580
Therefore, the lowest common multiple of 748,371,145,689 is 523102580.
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.
748 x 371 x 145 x 689 = 27724436740
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
371 : 1, 7, 53, 371
145 : 1, 5, 29, 145
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,371,145,689, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
371:7x 53
145:5x 29
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
53 = 53
Therefore, the value for common factors is 53.
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 = 27724436740/(1x53)
LCM = 27724436740/53
LCM = 523102580
Thus, we can understand that the LCM of 748,371,145,689 is 523102580.
