Given numbers are 692,689,899,657,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,689,899,657,742 is 1971280462788.
Find LCM of 692,689,899,657,742 with Prime Factorization
2 | 692, 689, 899, 657, 742 |
53 | 346, 689, 899, 657, 371 |
346, 13, 899, 657, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 346 x 13 x 899 x 657 x 7 = 1971280462788
Therefore, the lowest common multiple of 692,689,899,657,742 is 1971280462788.
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.
692 x 689 x 899 x 657 x 742 = 208955729055528
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.
692 : 1, 2, 4, 173, 346, 692
689 : 1, 13, 53, 689
899 : 1, 29, 31, 899
657 : 1, 3, 9, 73, 219, 657
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 692,689,899,657,742, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
689:13x 53
899:29x 31
657:3x 3x 73
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 53 = 106
Therefore, the value for common factors is 106.
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 = 208955729055528/(1x106)
LCM = 208955729055528/106
LCM = 1971280462788
Thus, we can understand that the LCM of 692,689,899,657,742 is 1971280462788.
