HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 790, 854 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 856, 790, 854 is 2 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 856, 790, 854 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 856, 790, 854 is 2.
HCF(856, 790, 854) = 2
HCF of 856, 790, 854 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 856, 790, 854 is 2.
Highest Common Factor of 856,790,854 is 2
Step 1: Since 856 > 790, we apply the division lemma to 856 and 790, to get
856 = 790 x 1 + 66
Step 2: Since the reminder 790 ≠ 0, we apply division lemma to 66 and 790, to get
790 = 66 x 11 + 64
Step 3: We consider the new divisor 66 and the new remainder 64, and apply the division lemma to get
66 = 64 x 1 + 2
We consider the new divisor 64 and the new remainder 2, and apply the division lemma to get
64 = 2 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 856 and 790 is 2
Notice that 2 = HCF(64,2) = HCF(66,64) = HCF(790,66) = HCF(856,790) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 854 > 2, we apply the division lemma to 854 and 2, to get
854 = 2 x 427 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 854 is 2
Notice that 2 = HCF(854,2) .
