HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 669, 606 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 669, 606 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 247, 669, 606 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 247, 669, 606 is 1.

HCF(247, 669, 606) = 1

HCF of 247, 669, 606 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 247, 669, 606 is 1.

Highest Common Factor of 247,669,606 using Euclid's algorithm

Highest Common Factor of 247,669,606 is 1

Step 1: Since 669 > 247, we apply the division lemma to 669 and 247, to get

669 = 247 x 2 + 175

Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 175 and 247, to get

247 = 175 x 1 + 72

Step 3: We consider the new divisor 175 and the new remainder 72, and apply the division lemma to get

175 = 72 x 2 + 31

We consider the new divisor 72 and the new remainder 31,and apply the division lemma to get

72 = 31 x 2 + 10

We consider the new divisor 31 and the new remainder 10,and apply the division lemma to get

31 = 10 x 3 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 669 is 1

Notice that 1 = HCF(10,1) = HCF(31,10) = HCF(72,31) = HCF(175,72) = HCF(247,175) = HCF(669,247) .

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

Step 1: Since 606 > 1, we apply the division lemma to 606 and 1, to get

606 = 1 x 606 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 606 is 1

Notice that 1 = HCF(606,1) .
