HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 850, 138, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 850, 138, 279 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 850, 138, 279 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 850, 138, 279 is 1.

HCF(850, 138, 279) = 1

HCF of 850, 138, 279 using Euclid's algorithm

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

Highest common factor (HCF) of 850, 138, 279 is 1.

Highest Common Factor of 850,138,279 using Euclid's algorithm

Highest Common Factor of 850,138,279 is 1

Step 1: Since 850 > 138, we apply the division lemma to 850 and 138, to get

850 = 138 x 6 + 22

Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 22 and 138, to get

138 = 22 x 6 + 6

Step 3: We consider the new divisor 22 and the new remainder 6, and apply the division lemma to get

22 = 6 x 3 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 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 850 and 138 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(138,22) = HCF(850,138) .


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

Step 1: Since 279 > 2, we apply the division lemma to 279 and 2, to get

279 = 2 x 139 + 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 279 is 1

Notice that 1 = HCF(2,1) = HCF(279,2) .
