HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 923, 531, 133 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 657, 923, 531, 133 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 657, 923, 531, 133 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 657, 923, 531, 133 is 1.

HCF(657, 923, 531, 133) = 1

Highest Common Factor of 657,923,531,133 using Euclid's algorithm

Highest Common Factor of 657,923,531,133 is 1

Step 1: Since 923 > 657, we apply the division lemma to 923 and 657, to get

923 = 657 x 1 + 266

Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 266 and 657, to get

657 = 266 x 2 + 125

Step 3: We consider the new divisor 266 and the new remainder 125, and apply the division lemma to get

266 = 125 x 2 + 16

We consider the new divisor 125 and the new remainder 16,and apply the division lemma to get

125 = 16 x 7 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 657 and 923 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(125,16) = HCF(266,125) = HCF(657,266) = HCF(923,657) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 531 > 1, we apply the division lemma to 531 and 1, to get

531 = 1 x 531 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 531 is 1

Notice that 1 = HCF(531,1) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 133 > 1, we apply the division lemma to 133 and 1, to get

133 = 1 x 133 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 133 is 1

Notice that 1 = HCF(133,1) .
