Find LCM of 902,170,728,611,749 with Prime Factorization
2 | 902, 170, 728, 611, 749 |
7 | 451, 85, 364, 611, 749 |
13 | 451, 85, 52, 611, 107 |
451, 85, 4, 47, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 451 x 85 x 4 x 47 x 107 = 140348728520
Therefore, the lowest common multiple of 902,170,728,611,749 is 140348728520.
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.
902 x 170 x 728 x 611 x 749 = 51086937181280
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
170 : 1, 2, 5, 10, 17, 34, 85, 170
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
611 : 1, 13, 47, 611
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,170,728,611,749, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
170:2x 5x 17
728:2x 2x 2x 7x 13
611:13x 47
749:7x 107
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 7x 13 = 364
Therefore, the value for common factors is 364.
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 = 51086937181280/(1x364)
LCM = 51086937181280/364
LCM = 140348728520
Thus, we can understand that the LCM of 902,170,728,611,749 is 140348728520.
