Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 23 x 1 x 297 x 4 x 47 x 1 = 1001697840
Therefore, the lowest common multiple of 690,891,624,611,460 is 1001697840.
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.
690 x 891 x 624 x 611 x 460 = 107822755497600
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
611 : 1, 13, 47, 611
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,891,624,611,460, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
891:3x 3x 3x 3x 11
624:2x 2x 2x 2x 3x 13
611:13x 47
460:2x 2x 5x 23
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 3x 3x 5x 13x 23 = 107640
Therefore, the value for common factors is 107640.
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 = 107822755497600/(1x107640)
LCM = 107822755497600/107640
LCM = 1001697840
Thus, we can understand that the LCM of 690,891,624,611,460 is 1001697840.
