HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 594, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 977, 594, 555 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 977, 594, 555 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 977, 594, 555 is 1.

HCF(977, 594, 555) = 1

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

HCF of:

Highest common factor (HCF) of 977, 594, 555 is 1.

Highest Common Factor of 977,594,555 using Euclid's algorithm

Highest Common Factor of 977,594,555 is 1

Step 1: Since 977 > 594, we apply the division lemma to 977 and 594, to get

977 = 594 x 1 + 383

Step 2: Since the reminder 594 ≠ 0, we apply division lemma to 383 and 594, to get

594 = 383 x 1 + 211

Step 3: We consider the new divisor 383 and the new remainder 211, and apply the division lemma to get

383 = 211 x 1 + 172

We consider the new divisor 211 and the new remainder 172,and apply the division lemma to get

211 = 172 x 1 + 39

We consider the new divisor 172 and the new remainder 39,and apply the division lemma to get

172 = 39 x 4 + 16

We consider the new divisor 39 and the new remainder 16,and apply the division lemma to get

39 = 16 x 2 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 594 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(39,16) = HCF(172,39) = HCF(211,172) = HCF(383,211) = HCF(594,383) = HCF(977,594) .

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

Step 1: Since 555 > 1, we apply the division lemma to 555 and 1, to get

555 = 1 x 555 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 555 is 1

Notice that 1 = HCF(555,1) .
