Find LCM of 556,396,781,266,728 with Prime Factorization
2 | 556, 396, 781, 266, 728 |
2 | 278, 198, 781, 133, 364 |
7 | 139, 99, 781, 133, 182 |
11 | 139, 99, 781, 19, 26 |
139, 9, 71, 19, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 139 x 9 x 71 x 19 x 26 = 13514292792
Therefore, the lowest common multiple of 556,396,781,266,728 is 13514292792.
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.
556 x 396 x 781 x 266 x 728 = 33299217439488
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.
556 : 1, 2, 4, 139, 278, 556
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
781 : 1, 11, 71, 781
266 : 1, 2, 7, 14, 19, 38, 133, 266
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,396,781,266,728, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
396:2x 2x 3x 3x 11
781:11x 71
266:2x 7x 19
728:2x 2x 2x 7x 13
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 2x 2x 7x 11 = 2464
Therefore, the value for common factors is 2464.
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 = 33299217439488/(1x2464)
LCM = 33299217439488/2464
LCM = 13514292792
Thus, we can understand that the LCM of 556,396,781,266,728 is 13514292792.
