Given numbers are 198,692,724,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,692,724,722 is 4476381228.
Find LCM of 198,692,724,722 with Prime Factorization
| 2 | 198, 692, 724, 722 |
| 2 | 99, 346, 362, 361 |
| 99, 173, 181, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 99 x 173 x 181 x 361 = 4476381228
Therefore, the lowest common multiple of 198,692,724,722 is 4476381228.
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.
198 x 692 x 724 x 722 = 71622099648
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
692 : 1, 2, 4, 173, 346, 692
724 : 1, 2, 4, 181, 362, 724
722 : 1, 2, 19, 38, 361, 722
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,692,724,722, is 2.
Now, the common factors can be found like this.
198:2x 3x 3x 11
692:2x 2x 173
724:2x 2x 181
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 71622099648/(2x8)
LCM = 71622099648/16
LCM = 4476381228
Thus, we can understand that the LCM of 198,692,724,722 is 4476381228.
