HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 49 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 342, 49 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 342, 49 is 1.
HCF(342, 49) = 1
HCF of 342, 49 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 49 is 1.
Highest Common Factor of 342,49 is 1
Step 1: Since 342 > 49, we apply the division lemma to 342 and 49, to get
342 = 49 x 6 + 48
Step 2: Since the reminder 49 ≠ 0, we apply division lemma to 48 and 49, to get
49 = 48 x 1 + 1
Step 3: We consider the new divisor 48 and the new remainder 1, and apply the division lemma to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 342 and 49 is 1
Notice that 1 = HCF(48,1) = HCF(49,48) = HCF(342,49) .
