HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 804, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 634, 804, 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 634, 804, 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 634, 804, 775 is 1.

HCF(634, 804, 775) = 1

Highest common factor (HCF) of 634, 804, 775 is 1.

Highest Common Factor of 634,804,775 using Euclid's algorithm

Highest Common Factor of 634,804,775 is 1

Step 1: Since 804 > 634, we apply the division lemma to 804 and 634, to get

804 = 634 x 1 + 170

Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 170 and 634, to get

634 = 170 x 3 + 124

Step 3: We consider the new divisor 170 and the new remainder 124, and apply the division lemma to get

170 = 124 x 1 + 46

We consider the new divisor 124 and the new remainder 46,and apply the division lemma to get

124 = 46 x 2 + 32

We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get

46 = 32 x 1 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 634 and 804 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(124,46) = HCF(170,124) = HCF(634,170) = HCF(804,634) .

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

Step 1: Since 775 > 2, we apply the division lemma to 775 and 2, to get

775 = 2 x 387 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 775 is 1

Notice that 1 = HCF(2,1) = HCF(775,2) .
