Given numbers are 781,437,611,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,437,611,966 is 8758363614.
Find LCM of 781,437,611,966 with Prime Factorization
23 | 781, 437, 611, 966 |
781, 19, 611, 42 |
Multiply the prime numbers at the bottom and the left side.
23 x 781 x 19 x 611 x 42 = 8758363614
Therefore, the lowest common multiple of 781,437,611,966 is 8758363614.
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 437 x 611 x 966 = 201442363122
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
437 : 1, 19, 23, 437
611 : 1, 13, 47, 611
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,437,611,966, is 1.
Now, the common factors can be found like this.
781:11x 71
437:19x 23
611:13x 47
966:2x 3x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 201442363122/(1x23)
LCM = 201442363122/23
LCM = 8758363614
Thus, we can understand that the LCM of 781,437,611,966 is 8758363614.
