Given numbers are 553,516,989,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 553,516,989,781 is 5125706124.
Find LCM of 553,516,989,781 with Prime Factorization
43 | 553, 516, 989, 781 |
553, 12, 23, 781 |
Multiply the prime numbers at the bottom and the left side.
43 x 553 x 12 x 23 x 781 = 5125706124
Therefore, the lowest common multiple of 553,516,989,781 is 5125706124.
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.
553 x 516 x 989 x 781 = 220405363332
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.
553 : 1, 7, 79, 553
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
989 : 1, 23, 43, 989
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,516,989,781, is 1.
Now, the common factors can be found like this.
553:7x 79
516:2x 2x 3x 43
989:23x 43
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 220405363332/(1x43)
LCM = 220405363332/43
LCM = 5125706124
Thus, we can understand that the LCM of 553,516,989,781 is 5125706124.
