Find LCM of 661,336,849,615,680 with Prime Factorization
2 | 661, 336, 849, 615, 680 |
2 | 661, 168, 849, 615, 340 |
2 | 661, 84, 849, 615, 170 |
3 | 661, 42, 849, 615, 85 |
5 | 661, 14, 283, 205, 85 |
661, 14, 283, 41, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 661 x 14 x 283 x 41 x 17 = 219043290480
Therefore, the lowest common multiple of 661,336,849,615,680 is 219043290480.
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.
661 x 336 x 849 x 615 x 680 = 78855584572800
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.
661 : 1, 661
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
849 : 1, 3, 283, 849
615 : 1, 3, 5, 15, 41, 123, 205, 615
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,336,849,615,680, is 1.
Now, the common factors can be found like this.
661:661
336:2x 2x 2x 2x 3x 7
849:3x 283
615:3x 5x 41
680:2x 2x 2x 5x 17
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 78855584572800/(1x360)
LCM = 78855584572800/360
LCM = 219043290480
Thus, we can understand that the LCM of 661,336,849,615,680 is 219043290480.
