Given numbers are 553,690,692,557

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

The LCM of 553,690,692,557 is 73536933540.

Find LCM of 553,690,692,557 with Prime Factorization

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

2 x 553 x 345 x 346 x 557 = 73536933540

Therefore, the lowest common multiple of 553,690,692,557 is 73536933540.

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.

553 x 690 x 692 x 557 = 147073867080

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.

553 : 1, 7, 79, 553

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

692 : 1, 2, 4, 173, 346, 692

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,690,692,557, is 1.

Now, the common factors can be found like this.

553:7x 79

690:2x 3x 5x 23

692:2x 2x 173

557:557

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 = 147073867080/(1x2)

LCM = 147073867080/2

LCM = 73536933540

Thus, we can understand that the LCM of 553,690,692,557 is 73536933540.
