HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 399, 131 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 399, 131 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 985, 399, 131 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 985, 399, 131 is 1.
HCF(985, 399, 131) = 1
HCF of 985, 399, 131 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 985, 399, 131 is 1.
Highest Common Factor of 985,399,131 is 1
Step 1: Since 985 > 399, we apply the division lemma to 985 and 399, to get
985 = 399 x 2 + 187
Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 187 and 399, to get
399 = 187 x 2 + 25
Step 3: We consider the new divisor 187 and the new remainder 25, and apply the division lemma to get
187 = 25 x 7 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 985 and 399 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(187,25) = HCF(399,187) = HCF(985,399) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 131 > 1, we apply the division lemma to 131 and 1, to get
131 = 1 x 131 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 131 is 1
Notice that 1 = HCF(131,1) .
