HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 394 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 394 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 868, 394 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 868, 394 is 2.
HCF(868, 394) = 2
HCF of 868, 394 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 394 is 2.
Highest Common Factor of 868,394 is 2
Step 1: Since 868 > 394, we apply the division lemma to 868 and 394, to get
868 = 394 x 2 + 80
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 80 and 394, to get
394 = 80 x 4 + 74
Step 3: We consider the new divisor 80 and the new remainder 74, and apply the division lemma to get
80 = 74 x 1 + 6
We consider the new divisor 74 and the new remainder 6,and apply the division lemma to get
74 = 6 x 12 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 868 and 394 is 2
Notice that 2 = HCF(6,2) = HCF(74,6) = HCF(80,74) = HCF(394,80) = HCF(868,394) .
