HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 895, 820 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 895, 820 is 5 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 895, 820 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 895, 820 is 5.
HCF(895, 820) = 5
HCF of 895, 820 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 895, 820 is 5.
Highest Common Factor of 895,820 is 5
Step 1: Since 895 > 820, we apply the division lemma to 895 and 820, to get
895 = 820 x 1 + 75
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 75 and 820, to get
820 = 75 x 10 + 70
Step 3: We consider the new divisor 75 and the new remainder 70, and apply the division lemma to get
75 = 70 x 1 + 5
We consider the new divisor 70 and the new remainder 5, and apply the division lemma to get
70 = 5 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 895 and 820 is 5
Notice that 5 = HCF(70,5) = HCF(75,70) = HCF(820,75) = HCF(895,820) .
