Given numbers are 896,406,938,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 896,406,938,421 is 732930688.
Find LCM of 896,406,938,421 with Prime Factorization
2 | 896, 406, 938, 421 |
7 | 448, 203, 469, 421 |
64, 29, 67, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 64 x 29 x 67 x 421 = 732930688
Therefore, the lowest common multiple of 896,406,938,421 is 732930688.
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.
896 x 406 x 938 x 421 = 143654414848
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
406 : 1, 2, 7, 14, 29, 58, 203, 406
938 : 1, 2, 7, 14, 67, 134, 469, 938
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,406,938,421, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
406:2x 7x 29
938:2x 7x 67
421:421
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 143654414848/(1x196)
LCM = 143654414848/196
LCM = 732930688
Thus, we can understand that the LCM of 896,406,938,421 is 732930688.
