Given numbers are 698,765,358,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,765,358,342 is 1816031970.
Find LCM of 698,765,358,342 with Prime Factorization
| 2 | 698, 765, 358, 342 |
| 3 | 349, 765, 179, 171 |
| 3 | 349, 255, 179, 57 |
| 349, 85, 179, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 349 x 85 x 179 x 19 = 1816031970
Therefore, the lowest common multiple of 698,765,358,342 is 1816031970.
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.
698 x 765 x 358 x 342 = 65377150920
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.
698 : 1, 2, 349, 698
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
358 : 1, 2, 179, 358
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,765,358,342, is 1.
Now, the common factors can be found like this.
698:2x 349
765:3x 3x 5x 17
358:2x 179
342:2x 3x 3x 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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 65377150920/(1x36)
LCM = 65377150920/36
LCM = 1816031970
Thus, we can understand that the LCM of 698,765,358,342 is 1816031970.
