Given numbers are 198,642,341,602
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,642,341,602 is 197686566.
Find LCM of 198,642,341,602 with Prime Factorization
| 2 | 198, 642, 341, 602 |
| 3 | 99, 321, 341, 301 |
| 11 | 33, 107, 341, 301 |
| 3, 107, 31, 301 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 3 x 107 x 31 x 301 = 197686566
Therefore, the lowest common multiple of 198,642,341,602 is 197686566.
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 642 x 341 x 602 = 26094626712
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
642 : 1, 2, 3, 6, 107, 214, 321, 642
341 : 1, 11, 31, 341
602 : 1, 2, 7, 14, 43, 86, 301, 602
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,642,341,602, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
642:2x 3x 107
341:11x 31
602:2x 7x 43
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 26094626712/(1x132)
LCM = 26094626712/132
LCM = 197686566
Thus, we can understand that the LCM of 198,642,341,602 is 197686566.
