HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 863, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 324, 863, 455 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 324, 863, 455 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 324, 863, 455 is 1.

HCF(324, 863, 455) = 1

HCF of 324, 863, 455 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 324, 863, 455 is 1.

Highest Common Factor of 324,863,455 using Euclid's algorithm

Highest Common Factor of 324,863,455 is 1

Step 1: Since 863 > 324, we apply the division lemma to 863 and 324, to get

863 = 324 x 2 + 215

Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 215 and 324, to get

324 = 215 x 1 + 109

Step 3: We consider the new divisor 215 and the new remainder 109, and apply the division lemma to get

215 = 109 x 1 + 106

We consider the new divisor 109 and the new remainder 106,and apply the division lemma to get

109 = 106 x 1 + 3

We consider the new divisor 106 and the new remainder 3,and apply the division lemma to get

106 = 3 x 35 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 324 and 863 is 1

Notice that 1 = HCF(3,1) = HCF(106,3) = HCF(109,106) = HCF(215,109) = HCF(324,215) = HCF(863,324) .

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

Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get

455 = 1 x 455 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1

Notice that 1 = HCF(455,1) .
