The LCM of 779,321,538,180,490 is 197761660740.
Find LCM of 779,321,538,180,490 with Prime Factorization
2 | 779, 321, 538, 180, 490 |
3 | 779, 321, 269, 90, 245 |
5 | 779, 107, 269, 30, 245 |
779, 107, 269, 6, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 779 x 107 x 269 x 6 x 49 = 197761660740
Therefore, the lowest common multiple of 779,321,538,180,490 is 197761660740.
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.
779 x 321 x 538 x 180 x 490 = 11865699644400
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.
779 : 1, 19, 41, 779
321 : 1, 3, 107, 321
538 : 1, 2, 269, 538
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,321,538,180,490, is 1.
Now, the common factors can be found like this.
779:19x 41
321:3x 107
538:2x 269
180:2x 2x 3x 3x 5
490:2x 5x 7x 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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 11865699644400/(1x60)
LCM = 11865699644400/60
LCM = 197761660740
Thus, we can understand that the LCM of 779,321,538,180,490 is 197761660740.
