Given numbers are 403,143,363,624,690

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

The LCM of 403,143,363,624,690 is 269171760.

Find LCM of 403,143,363,624,690 with Prime Factorization

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

2 x 3 x 11 x 13 x 31 x 1 x 11 x 8 x 115 = 269171760

Therefore, the lowest common multiple of 403,143,363,624,690 is 269171760.

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.

403 x 143 x 363 x 624 x 690 = 9007025433120

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.

403 : 1, 13, 31, 403

143 : 1, 11, 13, 143

363 : 1, 3, 11, 33, 121, 363

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,143,363,624,690, is 1.

Now, the common factors can be found like this.

403:13x 31

143:11x 13

363:3x 11x 11

624:2x 2x 2x 2x 3x 13

690:2x 3x 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 3x 3x 11x 13x 13 = 33462

Therefore, the value for common factors is 33462.

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 = 9007025433120/(1x33462)

LCM = 9007025433120/33462

LCM = 269171760

Thus, we can understand that the LCM of 403,143,363,624,690 is 269171760.
