HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 55, 11, 66, 622 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 55, 11, 66, 622 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 55, 11, 66, 622 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 55, 11, 66, 622 is 1.

HCF(55, 11, 66, 622) = 1

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

HCF of:

Highest common factor (HCF) of 55, 11, 66, 622 is 1.

Highest Common Factor of 55,11,66,622 using Euclid's algorithm

Highest Common Factor of 55,11,66,622 is 1

Step 1: Since 55 > 11, we apply the division lemma to 55 and 11, to get

55 = 11 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 55 and 11 is 11

Notice that 11 = HCF(55,11) .

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

Step 1: Since 66 > 11, we apply the division lemma to 66 and 11, to get

66 = 11 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 11 and 66 is 11

Notice that 11 = HCF(66,11) .

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

Step 1: Since 622 > 11, we apply the division lemma to 622 and 11, to get

622 = 11 x 56 + 6

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 6 and 11, to get

11 = 6 x 1 + 5

Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 622 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(622,11) .
