Find LCM of 880,432,612,421 with Prime Factorization
2 | 880, 432, 612, 421 |
2 | 440, 216, 306, 421 |
2 | 220, 108, 153, 421 |
2 | 110, 54, 153, 421 |
3 | 55, 27, 153, 421 |
3 | 55, 9, 51, 421 |
55, 3, 17, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 55 x 3 x 17 x 421 = 170050320
Therefore, the lowest common multiple of 880,432,612,421 is 170050320.
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.
880 x 432 x 612 x 421 = 97948984320
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.
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 880,432,612,421, is 1.
Now, the common factors can be found like this.
880:2x 2x 2x 2x 5x 11
432:2x 2x 2x 2x 3x 3x 3
612:2x 2x 3x 3x 17
421:421
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 2x 2x 2x 2x 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 97948984320/(1x576)
LCM = 97948984320/576
LCM = 170050320
Thus, we can understand that the LCM of 880,432,612,421 is 170050320.
