Find LCM of 892,280,392,611,639 with Prime Factorization
2 | 892, 280, 392, 611, 639 |
2 | 446, 140, 196, 611, 639 |
2 | 223, 70, 98, 611, 639 |
7 | 223, 35, 49, 611, 639 |
223, 5, 7, 611, 639 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 223 x 5 x 7 x 611 x 639 = 170648707320
Therefore, the lowest common multiple of 892,280,392,611,639 is 170648707320.
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.
892 x 280 x 392 x 611 x 639 = 38225310439680
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.
892 : 1, 2, 4, 223, 446, 892
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
611 : 1, 13, 47, 611
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,280,392,611,639, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
280:2x 2x 2x 5x 7
392:2x 2x 2x 7x 7
611:13x 47
639:3x 3x 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 2x 2x 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 38225310439680/(1x224)
LCM = 38225310439680/224
LCM = 170648707320
Thus, we can understand that the LCM of 892,280,392,611,639 is 170648707320.
