Given numbers are 428,300,640,938,835
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,300,640,938,835 is 80453385600.
Find LCM of 428,300,640,938,835 with Prime Factorization
2 | 428, 300, 640, 938, 835 |
2 | 214, 150, 320, 469, 835 |
5 | 107, 75, 160, 469, 835 |
107, 15, 32, 469, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 107 x 15 x 32 x 469 x 167 = 80453385600
Therefore, the lowest common multiple of 428,300,640,938,835 is 80453385600.
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.
428 x 300 x 640 x 938 x 835 = 64362708480000
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.
428 : 1, 2, 4, 107, 214, 428
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
938 : 1, 2, 7, 14, 67, 134, 469, 938
835 : 1, 5, 167, 835
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,300,640,938,835, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
300:2x 2x 3x 5x 5
640:2x 2x 2x 2x 2x 2x 2x 5
938:2x 7x 67
835:5x 167
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 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 64362708480000/(1x800)
LCM = 64362708480000/800
LCM = 80453385600
Thus, we can understand that the LCM of 428,300,640,938,835 is 80453385600.
