HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 66536 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 66536 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 423, 66536 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 423, 66536 is 1.
HCF(423, 66536) = 1
HCF of 423, 66536 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 423, 66536 is 1.
Highest Common Factor of 423,66536 is 1
Step 1: Since 66536 > 423, we apply the division lemma to 66536 and 423, to get
66536 = 423 x 157 + 125
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 125 and 423, to get
423 = 125 x 3 + 48
Step 3: We consider the new divisor 125 and the new remainder 48, and apply the division lemma to get
125 = 48 x 2 + 29
We consider the new divisor 48 and the new remainder 29,and apply the division lemma to get
48 = 29 x 1 + 19
We consider the new divisor 29 and the new remainder 19,and apply the division lemma to get
29 = 19 x 1 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 423 and 66536 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(29,19) = HCF(48,29) = HCF(125,48) = HCF(423,125) = HCF(66536,423) .
