HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 168 i.e. 24 the largest integer that leaves a remainder zero for all numbers.
HCF of 408, 168 is 24 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 408, 168 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 408, 168 is 24.
HCF(408, 168) = 24
HCF of 408, 168 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 408, 168 is 24.
Highest Common Factor of 408,168 is 24
Step 1: Since 408 > 168, we apply the division lemma to 408 and 168, to get
408 = 168 x 2 + 72
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 72 and 168, to get
168 = 72 x 2 + 24
Step 3: We consider the new divisor 72 and the new remainder 24, and apply the division lemma to get
72 = 24 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 408 and 168 is 24
Notice that 24 = HCF(72,24) = HCF(168,72) = HCF(408,168) .
