Find LCM of 535,781,748,420 with Prime Factorization
2 | 535, 781, 748, 420 |
2 | 535, 781, 374, 210 |
5 | 535, 781, 187, 105 |
11 | 107, 781, 187, 21 |
107, 71, 17, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 107 x 71 x 17 x 21 = 596668380
Therefore, the lowest common multiple of 535,781,748,420 is 596668380.
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.
535 x 781 x 748 x 420 = 131267043600
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.
535 : 1, 5, 107, 535
781 : 1, 11, 71, 781
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 535,781,748,420, is 1.
Now, the common factors can be found like this.
535:5x 107
781:11x 71
748:2x 2x 11x 17
420:2x 2x 3x 5x 7
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 131267043600/(1x220)
LCM = 131267043600/220
LCM = 596668380
Thus, we can understand that the LCM of 535,781,748,420 is 596668380.
