HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 775, 484, 998 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 775, 484, 998 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 775, 484, 998 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 775, 484, 998 is 1.

HCF(775, 484, 998) = 1

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

HCF of:

Highest common factor (HCF) of 775, 484, 998 is 1.

Highest Common Factor of 775,484,998 using Euclid's algorithm

Highest Common Factor of 775,484,998 is 1

Step 1: Since 775 > 484, we apply the division lemma to 775 and 484, to get

775 = 484 x 1 + 291

Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 291 and 484, to get

484 = 291 x 1 + 193

Step 3: We consider the new divisor 291 and the new remainder 193, and apply the division lemma to get

291 = 193 x 1 + 98

We consider the new divisor 193 and the new remainder 98,and apply the division lemma to get

193 = 98 x 1 + 95

We consider the new divisor 98 and the new remainder 95,and apply the division lemma to get

98 = 95 x 1 + 3

We consider the new divisor 95 and the new remainder 3,and apply the division lemma to get

95 = 3 x 31 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 775 and 484 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(95,3) = HCF(98,95) = HCF(193,98) = HCF(291,193) = HCF(484,291) = HCF(775,484) .

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

Step 1: Since 998 > 1, we apply the division lemma to 998 and 1, to get

998 = 1 x 998 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 998 is 1

Notice that 1 = HCF(998,1) .
