HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 469 i.e. 67 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 469 is 67 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 670, 469 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 670, 469 is 67.
HCF(670, 469) = 67
HCF of 670, 469 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 469 is 67.
Highest Common Factor of 670,469 is 67
Step 1: Since 670 > 469, we apply the division lemma to 670 and 469, to get
670 = 469 x 1 + 201
Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 201 and 469, to get
469 = 201 x 2 + 67
Step 3: We consider the new divisor 201 and the new remainder 67, and apply the division lemma to get
201 = 67 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 67, the HCF of 670 and 469 is 67
Notice that 67 = HCF(201,67) = HCF(469,201) = HCF(670,469) .
