HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 316, 332, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 316, 332, 421 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 316, 332, 421 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 316, 332, 421 is 1.
HCF(316, 332, 421) = 1
HCF of 316, 332, 421 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 316, 332, 421 is 1.
Highest Common Factor of 316,332,421 is 1
Step 1: Since 332 > 316, we apply the division lemma to 332 and 316, to get
332 = 316 x 1 + 16
Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 16 and 316, to get
316 = 16 x 19 + 12
Step 3: We consider the new divisor 16 and the new remainder 12, and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4, and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 316 and 332 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(316,16) = HCF(332,316) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 4, we apply the division lemma to 421 and 4, to get
421 = 4 x 105 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 421 is 1
Notice that 1 = HCF(4,1) = HCF(421,4) .
