HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 942, 322 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 394, 942, 322 is 2 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 394, 942, 322 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 394, 942, 322 is 2.
HCF(394, 942, 322) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 394, 942, 322 is 2.
Step 1: Since 942 > 394, we apply the division lemma to 942 and 394, to get
942 = 394 x 2 + 154
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 154 and 394, to get
394 = 154 x 2 + 86
Step 3: We consider the new divisor 154 and the new remainder 86, and apply the division lemma to get
154 = 86 x 1 + 68
We consider the new divisor 86 and the new remainder 68,and apply the division lemma to get
86 = 68 x 1 + 18
We consider the new divisor 68 and the new remainder 18,and apply the division lemma to get
68 = 18 x 3 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 394 and 942 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(68,18) = HCF(86,68) = HCF(154,86) = HCF(394,154) = HCF(942,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 322 > 2, we apply the division lemma to 322 and 2, to get
322 = 2 x 161 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 322 is 2
Notice that 2 = HCF(322,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
