Given numbers are 253,781,931,459,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,781,931,459,779 is 314720543907.
Find LCM of 253,781,931,459,779 with Prime Factorization
11 | 253, 781, 931, 459, 779 |
19 | 23, 71, 931, 459, 779 |
23, 71, 49, 459, 41 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 23 x 71 x 49 x 459 x 41 = 314720543907
Therefore, the lowest common multiple of 253,781,931,459,779 is 314720543907.
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.
253 x 781 x 931 x 459 x 779 = 65776593676563
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.
253 : 1, 11, 23, 253
781 : 1, 11, 71, 781
931 : 1, 7, 19, 49, 133, 931
459 : 1, 3, 9, 17, 27, 51, 153, 459
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,781,931,459,779, is 1.
Now, the common factors can be found like this.
253:11x 23
781:11x 71
931:7x 7x 19
459:3x 3x 3x 17
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 65776593676563/(1x209)
LCM = 65776593676563/209
LCM = 314720543907
Thus, we can understand that the LCM of 253,781,931,459,779 is 314720543907.
