Given numbers are 161,950,361,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,950,361,840 is 34872600.
Find LCM of 161,950,361,840 with Prime Factorization
2 | 161, 950, 361, 840 |
5 | 161, 475, 361, 420 |
7 | 161, 95, 361, 84 |
19 | 23, 95, 361, 12 |
23, 5, 19, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 19 x 23 x 5 x 19 x 12 = 34872600
Therefore, the lowest common multiple of 161,950,361,840 is 34872600.
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.
161 x 950 x 361 x 840 = 46380558000
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.
161 : 1, 7, 23, 161
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
361 : 1, 19, 361
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,950,361,840, is 1.
Now, the common factors can be found like this.
161:7x 23
950:2x 5x 5x 19
361:19x 19
840:2x 2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 19 = 1330
Therefore, the value for common factors is 1330.
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 = 46380558000/(1x1330)
LCM = 46380558000/1330
LCM = 34872600
Thus, we can understand that the LCM of 161,950,361,840 is 34872600.
