HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 329, 188, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 329, 188, 985 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 329, 188, 985 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 329, 188, 985 is 1.
HCF(329, 188, 985) = 1
HCF of 329, 188, 985 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 329, 188, 985 is 1.
Highest Common Factor of 329,188,985 is 1
Step 1: Since 329 > 188, we apply the division lemma to 329 and 188, to get
329 = 188 x 1 + 141
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 141 and 188, to get
188 = 141 x 1 + 47
Step 3: We consider the new divisor 141 and the new remainder 47, and apply the division lemma to get
141 = 47 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 47, the HCF of 329 and 188 is 47
Notice that 47 = HCF(141,47) = HCF(188,141) = HCF(329,188) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 985 > 47, we apply the division lemma to 985 and 47, to get
985 = 47 x 20 + 45
Step 2: Since the reminder 47 ≠ 0, we apply division lemma to 45 and 47, to get
47 = 45 x 1 + 2
Step 3: We consider the new divisor 45 and the new remainder 2, and apply the division lemma to get
45 = 2 x 22 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 47 and 985 is 1
Notice that 1 = HCF(2,1) = HCF(45,2) = HCF(47,45) = HCF(985,47) .
