Given numbers are 781,756,533,451,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,756,533,451,661 is 208018278468.
Find LCM of 781,756,533,451,661 with Prime Factorization
11 | 781, 756, 533, 451, 661 |
41 | 71, 756, 533, 41, 661 |
71, 756, 13, 1, 661 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 71 x 756 x 13 x 1 x 661 = 208018278468
Therefore, the lowest common multiple of 781,756,533,451,661 is 208018278468.
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 756 x 533 x 451 x 661 = 93816243589068
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
533 : 1, 13, 41, 533
451 : 1, 11, 41, 451
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,756,533,451,661, is 1.
Now, the common factors can be found like this.
781:11x 71
756:2x 2x 3x 3x 3x 7
533:13x 41
451:11x 41
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 41 = 451
Therefore, the value for common factors is 451.
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 = 93816243589068/(1x451)
LCM = 93816243589068/451
LCM = 208018278468
Thus, we can understand that the LCM of 781,756,533,451,661 is 208018278468.
