HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 243, 944 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 243, 944 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 434, 243, 944 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 434, 243, 944 is 1.
HCF(434, 243, 944) = 1
HCF of 434, 243, 944 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 434, 243, 944 is 1.
Highest Common Factor of 434,243,944 is 1
Step 1: Since 434 > 243, we apply the division lemma to 434 and 243, to get
434 = 243 x 1 + 191
Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 191 and 243, to get
243 = 191 x 1 + 52
Step 3: We consider the new divisor 191 and the new remainder 52, and apply the division lemma to get
191 = 52 x 3 + 35
We consider the new divisor 52 and the new remainder 35,and apply the division lemma to get
52 = 35 x 1 + 17
We consider the new divisor 35 and the new remainder 17,and apply the division lemma to get
35 = 17 x 2 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 434 and 243 is 1
Notice that 1 = HCF(17,1) = HCF(35,17) = HCF(52,35) = HCF(191,52) = HCF(243,191) = HCF(434,243) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 944 > 1, we apply the division lemma to 944 and 1, to get
944 = 1 x 944 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 944 is 1
Notice that 1 = HCF(944,1) .
