HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 646, 850 i.e. 34 the largest integer that leaves a remainder zero for all numbers.
HCF of 646, 850 is 34 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 646, 850 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 646, 850 is 34.
HCF(646, 850) = 34
HCF of 646, 850 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 646, 850 is 34.
Highest Common Factor of 646,850 is 34
Step 1: Since 850 > 646, we apply the division lemma to 850 and 646, to get
850 = 646 x 1 + 204
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 204 and 646, to get
646 = 204 x 3 + 34
Step 3: We consider the new divisor 204 and the new remainder 34, and apply the division lemma to get
204 = 34 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 646 and 850 is 34
Notice that 34 = HCF(204,34) = HCF(646,204) = HCF(850,646) .
