Given numbers are 578,440,495,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,440,495,781 is 81255240.
Find LCM of 578,440,495,781 with Prime Factorization
2 | 578, 440, 495, 781 |
5 | 289, 220, 495, 781 |
11 | 289, 44, 99, 781 |
289, 4, 9, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 289 x 4 x 9 x 71 = 81255240
Therefore, the lowest common multiple of 578,440,495,781 is 81255240.
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.
578 x 440 x 495 x 781 = 98318840400
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.
578 : 1, 2, 17, 34, 289, 578
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,440,495,781, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
440:2x 2x 2x 5x 11
495:3x 3x 5x 11
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.
2x 5x 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 98318840400/(1x1210)
LCM = 98318840400/1210
LCM = 81255240
Thus, we can understand that the LCM of 578,440,495,781 is 81255240.
