The LCM of 875,638,348,781,761 is 180976834500.
Find LCM of 875,638,348,781,761 with Prime Factorization
2 | 875, 638, 348, 781, 761 |
11 | 875, 319, 174, 781, 761 |
29 | 875, 29, 174, 71, 761 |
875, 1, 6, 71, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 875 x 1 x 6 x 71 x 761 = 180976834500
Therefore, the lowest common multiple of 875,638,348,781,761 is 180976834500.
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.
875 x 638 x 348 x 781 x 761 = 115463220411000
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
638 : 1, 2, 11, 22, 29, 58, 319, 638
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
781 : 1, 11, 71, 781
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,638,348,781,761, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
638:2x 11x 29
348:2x 2x 3x 29
781:11x 71
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 115463220411000/(1x638)
LCM = 115463220411000/638
LCM = 180976834500
Thus, we can understand that the LCM of 875,638,348,781,761 is 180976834500.
