HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 648, 546 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 551, 648, 546 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 551, 648, 546 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 551, 648, 546 is 1.

HCF(551, 648, 546) = 1

HCF of 551, 648, 546 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 551, 648, 546 is 1.

Highest Common Factor of 551,648,546 using Euclid's algorithm

Highest Common Factor of 551,648,546 is 1

Step 1: Since 648 > 551, we apply the division lemma to 648 and 551, to get

648 = 551 x 1 + 97

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 97 and 551, to get

551 = 97 x 5 + 66

Step 3: We consider the new divisor 97 and the new remainder 66, and apply the division lemma to get

97 = 66 x 1 + 31

We consider the new divisor 66 and the new remainder 31,and apply the division lemma to get

66 = 31 x 2 + 4

We consider the new divisor 31 and the new remainder 4,and apply the division lemma to get

31 = 4 x 7 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 551 and 648 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(66,31) = HCF(97,66) = HCF(551,97) = HCF(648,551) .

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

Step 1: Since 546 > 1, we apply the division lemma to 546 and 1, to get

546 = 1 x 546 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 546 is 1

Notice that 1 = HCF(546,1) .
