Given numbers are 781,654,616,60
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,654,616,60 is 71508360.
Find LCM of 781,654,616,60 with Prime Factorization
2 | 781, 654, 616, 60 |
2 | 781, 327, 308, 30 |
3 | 781, 327, 154, 15 |
11 | 781, 109, 154, 5 |
71, 109, 14, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 71 x 109 x 14 x 5 = 71508360
Therefore, the lowest common multiple of 781,654,616,60 is 71508360.
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 654 x 616 x 60 = 18878207040
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
654 : 1, 2, 3, 6, 109, 218, 327, 654
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,654,616,60, is 1.
Now, the common factors can be found like this.
781:11x 71
654:2x 3x 109
616:2x 2x 2x 7x 11
60:2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 18878207040/(1x264)
LCM = 18878207040/264
LCM = 71508360
Thus, we can understand that the LCM of 781,654,616,60 is 71508360.
