HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 55942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 841, 55942 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 841, 55942 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 841, 55942 is 1.
HCF(841, 55942) = 1
HCF of 841, 55942 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 841, 55942 is 1.
Highest Common Factor of 841,55942 is 1
Step 1: Since 55942 > 841, we apply the division lemma to 55942 and 841, to get
55942 = 841 x 66 + 436
Step 2: Since the reminder 841 ≠ 0, we apply division lemma to 436 and 841, to get
841 = 436 x 1 + 405
Step 3: We consider the new divisor 436 and the new remainder 405, and apply the division lemma to get
436 = 405 x 1 + 31
We consider the new divisor 405 and the new remainder 31,and apply the division lemma to get
405 = 31 x 13 + 2
We consider the new divisor 31 and the new remainder 2,and apply the division lemma to get
31 = 2 x 15 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 55942 is 1
Notice that 1 = HCF(2,1) = HCF(31,2) = HCF(405,31) = HCF(436,405) = HCF(841,436) = HCF(55942,841) .
