HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 929 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 421, 929 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, 929 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, 929 is 1.
HCF(421, 929) = 1
HCF of 421, 929 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, 929 is 1.
Highest Common Factor of 421,929 is 1
Step 1: Since 929 > 421, we apply the division lemma to 929 and 421, to get
929 = 421 x 2 + 87
Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 87 and 421, to get
421 = 87 x 4 + 73
Step 3: We consider the new divisor 87 and the new remainder 73, and apply the division lemma to get
87 = 73 x 1 + 14
We consider the new divisor 73 and the new remainder 14,and apply the division lemma to get
73 = 14 x 5 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 421 and 929 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(73,14) = HCF(87,73) = HCF(421,87) = HCF(929,421) .
