HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 146 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 421, 146 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 421, 146 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 421, 146 is 1.
HCF(421, 146) = 1
HCF of 421, 146 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 421, 146 is 1.
Highest Common Factor of 421,146 is 1
Step 1: Since 421 > 146, we apply the division lemma to 421 and 146, to get
421 = 146 x 2 + 129
Step 2: Since the reminder 146 ≠ 0, we apply division lemma to 129 and 146, to get
146 = 129 x 1 + 17
Step 3: We consider the new divisor 129 and the new remainder 17, and apply the division lemma to get
129 = 17 x 7 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 421 and 146 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(129,17) = HCF(146,129) = HCF(421,146) .
