HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 202, 349, 522, 445 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 202, 349, 522, 445 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 202, 349, 522, 445 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 202, 349, 522, 445 is 1.
HCF(202, 349, 522, 445) = 1
HCF of 202, 349, 522, 445 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 202, 349, 522, 445 is 1.
Highest Common Factor of 202,349,522,445 is 1
Step 1: Since 349 > 202, we apply the division lemma to 349 and 202, to get
349 = 202 x 1 + 147
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 147 and 202, to get
202 = 147 x 1 + 55
Step 3: We consider the new divisor 147 and the new remainder 55, and apply the division lemma to get
147 = 55 x 2 + 37
We consider the new divisor 55 and the new remainder 37,and apply the division lemma to get
55 = 37 x 1 + 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 202 and 349 is 1
Notice that 1 = HCF(18,1) = HCF(37,18) = HCF(55,37) = HCF(147,55) = HCF(202,147) = HCF(349,202) .
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) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 445 > 1, we apply the division lemma to 445 and 1, to get
445 = 1 x 445 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 445 is 1
Notice that 1 = HCF(445,1) .
