HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 441, 342 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 441, 342 is 9 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 441, 342 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 441, 342 is 9.
HCF(441, 342) = 9
HCF of 441, 342 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 441, 342 is 9.
Highest Common Factor of 441,342 is 9
Step 1: Since 441 > 342, we apply the division lemma to 441 and 342, to get
441 = 342 x 1 + 99
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 99 and 342, to get
342 = 99 x 3 + 45
Step 3: We consider the new divisor 99 and the new remainder 45, and apply the division lemma to get
99 = 45 x 2 + 9
We consider the new divisor 45 and the new remainder 9, and apply the division lemma to get
45 = 9 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 441 and 342 is 9
Notice that 9 = HCF(45,9) = HCF(99,45) = HCF(342,99) = HCF(441,342) .
