Given numbers are 502,771,357,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,771,357,278 is 6402061722.
Find LCM of 502,771,357,278 with Prime Factorization
| 2 | 502, 771, 357, 278 |
| 3 | 251, 771, 357, 139 |
| 251, 257, 119, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 251 x 257 x 119 x 139 = 6402061722
Therefore, the lowest common multiple of 502,771,357,278 is 6402061722.
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.
502 x 771 x 357 x 278 = 38412370332
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.
502 : 1, 2, 251, 502
771 : 1, 3, 257, 771
357 : 1, 3, 7, 17, 21, 51, 119, 357
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,771,357,278, is 1.
Now, the common factors can be found like this.
502:2x 251
771:3x 257
357:3x 7x 17
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 38412370332/(1x6)
LCM = 38412370332/6
LCM = 6402061722
Thus, we can understand that the LCM of 502,771,357,278 is 6402061722.
