Given numbers are 842,632,649,316
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,632,649,316 is 172680728.
Find LCM of 842,632,649,316 with Prime Factorization
| 2 | 842, 632, 649, 316 |
| 2 | 421, 316, 649, 158 |
| 79 | 421, 79, 649, 158 |
| 421, 1, 649, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 79 x 421 x 1 x 649 x 2 = 172680728
Therefore, the lowest common multiple of 842,632,649,316 is 172680728.
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.
842 x 632 x 649 x 316 = 109134220096
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.
842 : 1, 2, 421, 842
632 : 1, 2, 4, 8, 79, 158, 316, 632
649 : 1, 11, 59, 649
316 : 1, 2, 4, 79, 158, 316
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,632,649,316, is 1.
Now, the common factors can be found like this.
842:2x 421
632:2x 2x 2x 79
649:11x 59
316:2x 2x 79
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 2x 79 = 632
Therefore, the value for common factors is 632.
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 = 109134220096/(1x632)
LCM = 109134220096/632
LCM = 172680728
Thus, we can understand that the LCM of 842,632,649,316 is 172680728.
