Given numbers are 781,180,921,884,336
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,180,921,884,336 is 267062075280.
Find LCM of 781,180,921,884,336 with Prime Factorization
| 2 | 781, 180, 921, 884, 336 |
| 2 | 781, 90, 921, 442, 168 |
| 3 | 781, 45, 921, 221, 84 |
| 781, 15, 307, 221, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 781 x 15 x 307 x 221 x 28 = 267062075280
Therefore, the lowest common multiple of 781,180,921,884,336 is 267062075280.
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.
781 x 180 x 921 x 884 x 336 = 38456938840320
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.
781 : 1, 11, 71, 781
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
921 : 1, 3, 307, 921
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,180,921,884,336, is 1.
Now, the common factors can be found like this.
781:11x 71
180:2x 2x 3x 3x 5
921:3x 307
884:2x 2x 13x 17
336:2x 2x 2x 2x 3x 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 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 38456938840320/(1x144)
LCM = 38456938840320/144
LCM = 267062075280
Thus, we can understand that the LCM of 781,180,921,884,336 is 267062075280.
