HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 607 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 607 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 842, 607 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 842, 607 is 1.
HCF(842, 607) = 1
HCF of 842, 607 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 842, 607 is 1.
Highest Common Factor of 842,607 is 1
Step 1: Since 842 > 607, we apply the division lemma to 842 and 607, to get
842 = 607 x 1 + 235
Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 235 and 607, to get
607 = 235 x 2 + 137
Step 3: We consider the new divisor 235 and the new remainder 137, and apply the division lemma to get
235 = 137 x 1 + 98
We consider the new divisor 137 and the new remainder 98,and apply the division lemma to get
137 = 98 x 1 + 39
We consider the new divisor 98 and the new remainder 39,and apply the division lemma to get
98 = 39 x 2 + 20
We consider the new divisor 39 and the new remainder 20,and apply the division lemma to get
39 = 20 x 1 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 842 and 607 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(39,20) = HCF(98,39) = HCF(137,98) = HCF(235,137) = HCF(607,235) = HCF(842,607) .
