Given numbers are 781,388,497,776
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,388,497,776 is 4242392.
Find LCM of 781,388,497,776 with Prime Factorization
2 | 781, 388, 497, 776 |
2 | 781, 194, 497, 388 |
71 | 781, 97, 497, 194 |
97 | 11, 97, 7, 194 |
11, 1, 7, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 97 x 11 x 1 x 7 x 2 = 4242392
Therefore, the lowest common multiple of 781,388,497,776 is 4242392.
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.
781 x 388 x 497 x 776 = 116869414816
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.
781 : 1, 11, 71, 781
388 : 1, 2, 4, 97, 194, 388
497 : 1, 7, 71, 497
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,388,497,776, is 1.
Now, the common factors can be found like this.
781:11x 71
388:2x 2x 97
497:7x 71
776:2x 2x 2x 97
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 71x 97 = 27548
Therefore, the value for common factors is 27548.
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 = 116869414816/(1x27548)
LCM = 116869414816/27548
LCM = 4242392
Thus, we can understand that the LCM of 781,388,497,776 is 4242392.
