HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 23744 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 23744 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 621, 23744 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 621, 23744 is 1.
HCF(621, 23744) = 1
HCF of 621, 23744 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 23744 is 1.
Highest Common Factor of 621,23744 is 1
Step 1: Since 23744 > 621, we apply the division lemma to 23744 and 621, to get
23744 = 621 x 38 + 146
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 146 and 621, to get
621 = 146 x 4 + 37
Step 3: We consider the new divisor 146 and the new remainder 37, and apply the division lemma to get
146 = 37 x 3 + 35
We consider the new divisor 37 and the new remainder 35,and apply the division lemma to get
37 = 35 x 1 + 2
We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get
35 = 2 x 17 + 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 621 and 23744 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(37,35) = HCF(146,37) = HCF(621,146) = HCF(23744,621) .
