HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 131, 644, 312 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 131, 644, 312 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 131, 644, 312 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 131, 644, 312 is 1.
HCF(131, 644, 312) = 1
HCF of 131, 644, 312 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 131, 644, 312 is 1.
Highest Common Factor of 131,644,312 is 1
Step 1: Since 644 > 131, we apply the division lemma to 644 and 131, to get
644 = 131 x 4 + 120
Step 2: Since the reminder 131 ≠ 0, we apply division lemma to 120 and 131, to get
131 = 120 x 1 + 11
Step 3: We consider the new divisor 120 and the new remainder 11, and apply the division lemma to get
120 = 11 x 10 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 131 and 644 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(120,11) = HCF(131,120) = HCF(644,131) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 312 > 1, we apply the division lemma to 312 and 1, to get
312 = 1 x 312 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 312 is 1
Notice that 1 = HCF(312,1) .
