Given numbers are 475,781,787,700
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,781,787,700 is 8174805100.
Find LCM of 475,781,787,700 with Prime Factorization
| 5 | 475, 781, 787, 700 |
| 5 | 95, 781, 787, 140 |
| 19, 781, 787, 28 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 19 x 781 x 787 x 28 = 8174805100
Therefore, the lowest common multiple of 475,781,787,700 is 8174805100.
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.
475 x 781 x 787 x 700 = 204370127500
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.
475 : 1, 5, 19, 25, 95, 475
781 : 1, 11, 71, 781
787 : 1, 787
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,781,787,700, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
781:11x 71
787:787
700:2x 2x 5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 204370127500/(1x25)
LCM = 204370127500/25
LCM = 8174805100
Thus, we can understand that the LCM of 475,781,787,700 is 8174805100.
