Given numbers are 670,979,338,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,979,338,681 is 75490327770.
Find LCM of 670,979,338,681 with Prime Factorization
2 | 670, 979, 338, 681 |
335, 979, 169, 681 |
Multiply the prime numbers at the bottom and the left side.
2 x 335 x 979 x 169 x 681 = 75490327770
Therefore, the lowest common multiple of 670,979,338,681 is 75490327770.
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.
670 x 979 x 338 x 681 = 150980655540
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
979 : 1, 11, 89, 979
338 : 1, 2, 13, 26, 169, 338
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,979,338,681, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
979:11x 89
338:2x 13x 13
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 150980655540/(1x2)
LCM = 150980655540/2
LCM = 75490327770
Thus, we can understand that the LCM of 670,979,338,681 is 75490327770.
