Find LCM of 688,609,946,769,124 with Prime Factorization
2 | 688, 609, 946, 769, 124 |
2 | 344, 609, 473, 769, 62 |
43 | 172, 609, 473, 769, 31 |
4, 609, 11, 769, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 4 x 609 x 11 x 769 x 31 = 109871853168
Therefore, the lowest common multiple of 688,609,946,769,124 is 109871853168.
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.
688 x 609 x 946 x 769 x 124 = 37795917489792
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
609 : 1, 3, 7, 21, 29, 87, 203, 609
946 : 1, 2, 11, 22, 43, 86, 473, 946
769 : 1, 769
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,609,946,769,124, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
609:3x 7x 29
946:2x 11x 43
769:769
124:2x 2x 31
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 43 = 344
Therefore, the value for common factors is 344.
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 = 37795917489792/(1x344)
LCM = 37795917489792/344
LCM = 109871853168
Thus, we can understand that the LCM of 688,609,946,769,124 is 109871853168.
