HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 704, 842 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 704, 842 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 704, 842 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 704, 842 is 2.
HCF(704, 842) = 2
HCF of 704, 842 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 704, 842 is 2.
Highest Common Factor of 704,842 is 2
Step 1: Since 842 > 704, we apply the division lemma to 842 and 704, to get
842 = 704 x 1 + 138
Step 2: Since the reminder 704 ≠ 0, we apply division lemma to 138 and 704, to get
704 = 138 x 5 + 14
Step 3: We consider the new divisor 138 and the new remainder 14, and apply the division lemma to get
138 = 14 x 9 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 704 and 842 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(138,14) = HCF(704,138) = HCF(842,704) .
