Given numbers are 690,661,251,652

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 690,661,251,652 is 37320020340.

Find LCM of 690,661,251,652 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 345 x 661 x 251 x 326 = 37320020340

Therefore, the lowest common multiple of 690,661,251,652 is 37320020340.

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 661 x 251 x 652 = 74640040680

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

661 : 1, 661

251 : 1, 251

652 : 1, 2, 4, 163, 326, 652

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,661,251,652, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

661:661

251:251

652:2x 2x 163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 74640040680/(1x2)

LCM = 74640040680/2

LCM = 37320020340

Thus, we can understand that the LCM of 690,661,251,652 is 37320020340.
