HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 192, 549, 349, 977 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 192, 549, 349, 977 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 192, 549, 349, 977 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 192, 549, 349, 977 is 1.
HCF(192, 549, 349, 977) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 192, 549, 349, 977 is 1.
Step 1: Since 549 > 192, we apply the division lemma to 549 and 192, to get
549 = 192 x 2 + 165
Step 2: Since the reminder 192 ≠ 0, we apply division lemma to 165 and 192, to get
192 = 165 x 1 + 27
Step 3: We consider the new divisor 165 and the new remainder 27, and apply the division lemma to get
165 = 27 x 6 + 3
We consider the new divisor 27 and the new remainder 3, and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 192 and 549 is 3
Notice that 3 = HCF(27,3) = HCF(165,27) = HCF(192,165) = HCF(549,192) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 349 > 3, we apply the division lemma to 349 and 3, to get
349 = 3 x 116 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 349 is 1
Notice that 1 = HCF(3,1) = HCF(349,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 977 > 1, we apply the division lemma to 977 and 1, to get
977 = 1 x 977 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 977 is 1
Notice that 1 = HCF(977,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
