HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 163, 145, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 163, 145, 394 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 163, 145, 394 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 163, 145, 394 is 1.
HCF(163, 145, 394) = 1
HCF of 163, 145, 394 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 163, 145, 394 is 1.
Highest Common Factor of 163,145,394 is 1
Step 1: Since 163 > 145, we apply the division lemma to 163 and 145, to get
163 = 145 x 1 + 18
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 18 and 145, to get
145 = 18 x 8 + 1
Step 3: We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 163 and 145 is 1
Notice that 1 = HCF(18,1) = HCF(145,18) = HCF(163,145) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get
394 = 1 x 394 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1
Notice that 1 = HCF(394,1) .
