HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 639, 423 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 807, 639, 423 is 3 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 807, 639, 423 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 807, 639, 423 is 3.
HCF(807, 639, 423) = 3
HCF of 807, 639, 423 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 807, 639, 423 is 3.
Highest Common Factor of 807,639,423 is 3
Step 1: Since 807 > 639, we apply the division lemma to 807 and 639, to get
807 = 639 x 1 + 168
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 168 and 639, to get
639 = 168 x 3 + 135
Step 3: We consider the new divisor 168 and the new remainder 135, and apply the division lemma to get
168 = 135 x 1 + 33
We consider the new divisor 135 and the new remainder 33,and apply the division lemma to get
135 = 33 x 4 + 3
We consider the new divisor 33 and the new remainder 3,and apply the division lemma to get
33 = 3 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 807 and 639 is 3
Notice that 3 = HCF(33,3) = HCF(135,33) = HCF(168,135) = HCF(639,168) = HCF(807,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 423 > 3, we apply the division lemma to 423 and 3, to get
423 = 3 x 141 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 423 is 3
Notice that 3 = HCF(423,3) .
