HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 773, 557, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 773, 557, 775 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 773, 557, 775 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 773, 557, 775 is 1.

HCF(773, 557, 775) = 1

HCF of 773, 557, 775 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 773, 557, 775 is 1.

Highest Common Factor of 773,557,775 using Euclid's algorithm

Highest Common Factor of 773,557,775 is 1

Step 1: Since 773 > 557, we apply the division lemma to 773 and 557, to get

773 = 557 x 1 + 216

Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 216 and 557, to get

557 = 216 x 2 + 125

Step 3: We consider the new divisor 216 and the new remainder 125, and apply the division lemma to get

216 = 125 x 1 + 91

We consider the new divisor 125 and the new remainder 91,and apply the division lemma to get

125 = 91 x 1 + 34

We consider the new divisor 91 and the new remainder 34,and apply the division lemma to get

91 = 34 x 2 + 23

We consider the new divisor 34 and the new remainder 23,and apply the division lemma to get

34 = 23 x 1 + 11

We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get

23 = 11 x 2 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 773 and 557 is 1

Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(91,34) = HCF(125,91) = HCF(216,125) = HCF(557,216) = HCF(773,557) .

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

Step 1: Since 775 > 1, we apply the division lemma to 775 and 1, to get

775 = 1 x 775 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 775 is 1

Notice that 1 = HCF(775,1) .
