HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 7345 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 7345 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, 7345 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, 7345 is 1.
HCF(842, 7345) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 842, 7345 is 1.
Step 1: Since 7345 > 842, we apply the division lemma to 7345 and 842, to get
7345 = 842 x 8 + 609
Step 2: Since the reminder 842 ≠ 0, we apply division lemma to 609 and 842, to get
842 = 609 x 1 + 233
Step 3: We consider the new divisor 609 and the new remainder 233, and apply the division lemma to get
609 = 233 x 2 + 143
We consider the new divisor 233 and the new remainder 143,and apply the division lemma to get
233 = 143 x 1 + 90
We consider the new divisor 143 and the new remainder 90,and apply the division lemma to get
143 = 90 x 1 + 53
We consider the new divisor 90 and the new remainder 53,and apply the division lemma to get
90 = 53 x 1 + 37
We consider the new divisor 53 and the new remainder 37,and apply the division lemma to get
53 = 37 x 1 + 16
We consider the new divisor 37 and the new remainder 16,and apply the division lemma to get
37 = 16 x 2 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 842 and 7345 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(37,16) = HCF(53,37) = HCF(90,53) = HCF(143,90) = HCF(233,143) = HCF(609,233) = HCF(842,609) = HCF(7345,842) .
Here are some samples of HCF using Euclid's Algorithm calculations.
