HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 424 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 424 is 2 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 658, 424 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 658, 424 is 2.
HCF(658, 424) = 2
HCF of 658, 424 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 658, 424 is 2.
Highest Common Factor of 658,424 is 2
Step 1: Since 658 > 424, we apply the division lemma to 658 and 424, to get
658 = 424 x 1 + 234
Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 234 and 424, to get
424 = 234 x 1 + 190
Step 3: We consider the new divisor 234 and the new remainder 190, and apply the division lemma to get
234 = 190 x 1 + 44
We consider the new divisor 190 and the new remainder 44,and apply the division lemma to get
190 = 44 x 4 + 14
We consider the new divisor 44 and the new remainder 14,and apply the division lemma to get
44 = 14 x 3 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 658 and 424 is 2
Notice that 2 = HCF(14,2) = HCF(44,14) = HCF(190,44) = HCF(234,190) = HCF(424,234) = HCF(658,424) .
