HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 256, 612 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 394, 256, 612 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, 256, 612 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, 256, 612 is 2.
HCF(394, 256, 612) = 2
HCF of 394, 256, 612 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 394, 256, 612 is 2.
Highest Common Factor of 394,256,612 is 2
Step 1: Since 394 > 256, we apply the division lemma to 394 and 256, to get
394 = 256 x 1 + 138
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 138 and 256, to get
256 = 138 x 1 + 118
Step 3: We consider the new divisor 138 and the new remainder 118, and apply the division lemma to get
138 = 118 x 1 + 20
We consider the new divisor 118 and the new remainder 20,and apply the division lemma to get
118 = 20 x 5 + 18
We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get
20 = 18 x 1 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 394 and 256 is 2
Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(118,20) = HCF(138,118) = HCF(256,138) = HCF(394,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 612 > 2, we apply the division lemma to 612 and 2, to get
612 = 2 x 306 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 612 is 2
Notice that 2 = HCF(612,2) .
