Given numbers are 749,812,793,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,812,793,421 is 29006484052.
Find LCM of 749,812,793,421 with Prime Factorization
7 | 749, 812, 793, 421 |
107, 116, 793, 421 |
Multiply the prime numbers at the bottom and the left side.
7 x 107 x 116 x 793 x 421 = 29006484052
Therefore, the lowest common multiple of 749,812,793,421 is 29006484052.
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.
749 x 812 x 793 x 421 = 203045388364
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.
749 : 1, 7, 107, 749
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
793 : 1, 13, 61, 793
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,812,793,421, is 1.
Now, the common factors can be found like this.
749:7x 107
812:2x 2x 7x 29
793:13x 61
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.
7 = 7
Therefore, the value for common factors is 7.
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 = 203045388364/(1x7)
LCM = 203045388364/7
LCM = 29006484052
Thus, we can understand that the LCM of 749,812,793,421 is 29006484052.
