HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 792, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 792, 421 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 792, 421 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 792, 421 is 1.
HCF(792, 421) = 1
HCF of 792, 421 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 792, 421 is 1.
Highest Common Factor of 792,421 is 1
Step 1: Since 792 > 421, we apply the division lemma to 792 and 421, to get
792 = 421 x 1 + 371
Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 371 and 421, to get
421 = 371 x 1 + 50
Step 3: We consider the new divisor 371 and the new remainder 50, and apply the division lemma to get
371 = 50 x 7 + 21
We consider the new divisor 50 and the new remainder 21,and apply the division lemma to get
50 = 21 x 2 + 8
We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get
21 = 8 x 2 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 792 and 421 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(50,21) = HCF(371,50) = HCF(421,371) = HCF(792,421) .
