Given numbers are 781,544,817,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,544,817,475 is 8677847200.
Find LCM of 781,544,817,475 with Prime Factorization
19 | 781, 544, 817, 475 |
781, 544, 43, 25 |
Multiply the prime numbers at the bottom and the left side.
19 x 781 x 544 x 43 x 25 = 8677847200
Therefore, the lowest common multiple of 781,544,817,475 is 8677847200.
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 544 x 817 x 475 = 164879096800
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
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
817 : 1, 19, 43, 817
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,544,817,475, is 1.
Now, the common factors can be found like this.
781:11x 71
544:2x 2x 2x 2x 2x 17
817:19x 43
475:5x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 164879096800/(1x19)
LCM = 164879096800/19
LCM = 8677847200
Thus, we can understand that the LCM of 781,544,817,475 is 8677847200.
