HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 351, 850, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 864, 351, 850, 644 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 864, 351, 850, 644 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 864, 351, 850, 644 is 1.

HCF(864, 351, 850, 644) = 1

HCF of 864, 351, 850, 644 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 864, 351, 850, 644 is 1.

Highest Common Factor of 864,351,850,644 using Euclid's algorithm

Highest Common Factor of 864,351,850,644 is 1

Step 1: Since 864 > 351, we apply the division lemma to 864 and 351, to get

864 = 351 x 2 + 162

Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 162 and 351, to get

351 = 162 x 2 + 27

Step 3: We consider the new divisor 162 and the new remainder 27, and apply the division lemma to get

162 = 27 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 864 and 351 is 27

Notice that 27 = HCF(162,27) = HCF(351,162) = HCF(864,351) .


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

Step 1: Since 850 > 27, we apply the division lemma to 850 and 27, to get

850 = 27 x 31 + 13

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 13 and 27, to get

27 = 13 x 2 + 1

Step 3: We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 850 is 1

Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(850,27) .


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

Step 1: Since 644 > 1, we apply the division lemma to 644 and 1, to get

644 = 1 x 644 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 644 is 1

Notice that 1 = HCF(644,1) .
