HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 850, 808 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 850, 808 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 68, 850, 808 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 68, 850, 808 is 2.
HCF(68, 850, 808) = 2
HCF of 68, 850, 808 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 850, 808 is 2.
Highest Common Factor of 68,850,808 is 2
Step 1: Since 850 > 68, we apply the division lemma to 850 and 68, to get
850 = 68 x 12 + 34
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 34 and 68, to get
68 = 34 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 68 and 850 is 34
Notice that 34 = HCF(68,34) = HCF(850,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 808 > 34, we apply the division lemma to 808 and 34, to get
808 = 34 x 23 + 26
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 26 and 34, to get
34 = 26 x 1 + 8
Step 3: We consider the new divisor 26 and the new remainder 8, and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 34 and 808 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(34,26) = HCF(808,34) .
