Given numbers are 761,247,779,858,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 761,247,779,858,245 is 124616481990.
Find LCM of 761,247,779,858,245 with Prime Factorization
13 | 761, 247, 779, 858, 245 |
19 | 761, 19, 779, 66, 245 |
761, 1, 41, 66, 245 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 761 x 1 x 41 x 66 x 245 = 124616481990
Therefore, the lowest common multiple of 761,247,779,858,245 is 124616481990.
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.
761 x 247 x 779 x 858 x 245 = 30780271051530
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.
761 : 1, 761
247 : 1, 13, 19, 247
779 : 1, 19, 41, 779
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,247,779,858,245, is 1.
Now, the common factors can be found like this.
761:761
247:13x 19
779:19x 41
858:2x 3x 11x 13
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 30780271051530/(1x247)
LCM = 30780271051530/247
LCM = 124616481990
Thus, we can understand that the LCM of 761,247,779,858,245 is 124616481990.
