HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 65370 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 65370 is 1 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 811, 65370 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 811, 65370 is 1.
HCF(811, 65370) = 1
HCF of 811, 65370 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 811, 65370 is 1.
Highest Common Factor of 811,65370 is 1
Step 1: Since 65370 > 811, we apply the division lemma to 65370 and 811, to get
65370 = 811 x 80 + 490
Step 2: Since the reminder 811 ≠ 0, we apply division lemma to 490 and 811, to get
811 = 490 x 1 + 321
Step 3: We consider the new divisor 490 and the new remainder 321, and apply the division lemma to get
490 = 321 x 1 + 169
We consider the new divisor 321 and the new remainder 169,and apply the division lemma to get
321 = 169 x 1 + 152
We consider the new divisor 169 and the new remainder 152,and apply the division lemma to get
169 = 152 x 1 + 17
We consider the new divisor 152 and the new remainder 17,and apply the division lemma to get
152 = 17 x 8 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 65370 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(152,17) = HCF(169,152) = HCF(321,169) = HCF(490,321) = HCF(811,490) = HCF(65370,811) .
