HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 350, 914, 522 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 221, 350, 914, 522 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 221, 350, 914, 522 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 221, 350, 914, 522 is 1.
HCF(221, 350, 914, 522) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 221, 350, 914, 522 is 1.
Step 1: Since 350 > 221, we apply the division lemma to 350 and 221, to get
350 = 221 x 1 + 129
Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 129 and 221, to get
221 = 129 x 1 + 92
Step 3: We consider the new divisor 129 and the new remainder 92, and apply the division lemma to get
129 = 92 x 1 + 37
We consider the new divisor 92 and the new remainder 37,and apply the division lemma to get
92 = 37 x 2 + 18
We consider the new divisor 37 and the new remainder 18,and apply the division lemma to get
37 = 18 x 2 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 221 and 350 is 1
Notice that 1 = HCF(18,1) = HCF(37,18) = HCF(92,37) = HCF(129,92) = HCF(221,129) = HCF(350,221) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 914 > 1, we apply the division lemma to 914 and 1, to get
914 = 1 x 914 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 914 is 1
Notice that 1 = HCF(914,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 522 > 1, we apply the division lemma to 522 and 1, to get
522 = 1 x 522 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 522 is 1
Notice that 1 = HCF(522,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
