Find LCM of 420,883,659,172,978 with Prime Factorization
2 | 420, 883, 659, 172, 978 |
2 | 210, 883, 659, 86, 489 |
3 | 105, 883, 659, 43, 489 |
35, 883, 659, 43, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 35 x 883 x 659 x 43 x 163 = 1712976750660
Therefore, the lowest common multiple of 420,883,659,172,978 is 1712976750660.
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.
420 x 883 x 659 x 172 x 978 = 41111442015840
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.
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
883 : 1, 883
659 : 1, 659
172 : 1, 2, 4, 43, 86, 172
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,883,659,172,978, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
883:883
659:659
172:2x 2x 43
978:2x 3x 163
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 3 = 24
Therefore, the value for common factors is 24.
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 = 41111442015840/(1x24)
LCM = 41111442015840/24
LCM = 1712976750660
Thus, we can understand that the LCM of 420,883,659,172,978 is 1712976750660.
