HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 771, 553 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 771, 553 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 771, 553 is 1.

HCF(771, 553) = 1

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

HCF of:

Highest common factor (HCF) of 771, 553 is 1.

Highest Common Factor of 771,553 using Euclid's algorithm

Highest Common Factor of 771,553 is 1

Step 1: Since 771 > 553, we apply the division lemma to 771 and 553, to get

771 = 553 x 1 + 218

Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 218 and 553, to get

553 = 218 x 2 + 117

Step 3: We consider the new divisor 218 and the new remainder 117, and apply the division lemma to get

218 = 117 x 1 + 101

We consider the new divisor 117 and the new remainder 101,and apply the division lemma to get

117 = 101 x 1 + 16

We consider the new divisor 101 and the new remainder 16,and apply the division lemma to get

101 = 16 x 6 + 5

We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get

16 = 5 x 3 + 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 771 and 553 is 1

Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(101,16) = HCF(117,101) = HCF(218,117) = HCF(553,218) = HCF(771,553) .
