HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 363, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 218, 363, 857 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 218, 363, 857 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 218, 363, 857 is 1.

HCF(218, 363, 857) = 1

HCF of 218, 363, 857 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 218, 363, 857 is 1.

Highest Common Factor of 218,363,857 using Euclid's algorithm

Highest Common Factor of 218,363,857 is 1

Step 1: Since 363 > 218, we apply the division lemma to 363 and 218, to get

363 = 218 x 1 + 145

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 145 and 218, to get

218 = 145 x 1 + 73

Step 3: We consider the new divisor 145 and the new remainder 73, and apply the division lemma to get

145 = 73 x 1 + 72

We consider the new divisor 73 and the new remainder 72,and apply the division lemma to get

73 = 72 x 1 + 1

We consider the new divisor 72 and the new remainder 1,and apply the division lemma to get

72 = 1 x 72 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 218 and 363 is 1

Notice that 1 = HCF(72,1) = HCF(73,72) = HCF(145,73) = HCF(218,145) = HCF(363,218) .


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

Step 1: Since 857 > 1, we apply the division lemma to 857 and 1, to get

857 = 1 x 857 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 857 is 1

Notice that 1 = HCF(857,1) .
