HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 853, 329 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 853, 329 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 981, 853, 329 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 981, 853, 329 is 1.
HCF(981, 853, 329) = 1
HCF of 981, 853, 329 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 981, 853, 329 is 1.
Highest Common Factor of 981,853,329 is 1
Step 1: Since 981 > 853, we apply the division lemma to 981 and 853, to get
981 = 853 x 1 + 128
Step 2: Since the reminder 853 ≠ 0, we apply division lemma to 128 and 853, to get
853 = 128 x 6 + 85
Step 3: We consider the new divisor 128 and the new remainder 85, and apply the division lemma to get
128 = 85 x 1 + 43
We consider the new divisor 85 and the new remainder 43,and apply the division lemma to get
85 = 43 x 1 + 42
We consider the new divisor 43 and the new remainder 42,and apply the division lemma to get
43 = 42 x 1 + 1
We consider the new divisor 42 and the new remainder 1,and apply the division lemma to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 981 and 853 is 1
Notice that 1 = HCF(42,1) = HCF(43,42) = HCF(85,43) = HCF(128,85) = HCF(853,128) = HCF(981,853) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 329 > 1, we apply the division lemma to 329 and 1, to get
329 = 1 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 329 is 1
Notice that 1 = HCF(329,1) .
