HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 411, 72845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 411, 72845 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 411, 72845 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 411, 72845 is 1.
HCF(411, 72845) = 1
HCF of 411, 72845 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 411, 72845 is 1.
Highest Common Factor of 411,72845 is 1
Step 1: Since 72845 > 411, we apply the division lemma to 72845 and 411, to get
72845 = 411 x 177 + 98
Step 2: Since the reminder 411 ≠ 0, we apply division lemma to 98 and 411, to get
411 = 98 x 4 + 19
Step 3: We consider the new divisor 98 and the new remainder 19, and apply the division lemma to get
98 = 19 x 5 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 411 and 72845 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(98,19) = HCF(411,98) = HCF(72845,411) .
