HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 173, 830 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 173, 830 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 497, 173, 830 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 497, 173, 830 is 1.
HCF(497, 173, 830) = 1
HCF of 497, 173, 830 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 173, 830 is 1.
Highest Common Factor of 497,173,830 is 1
Step 1: Since 497 > 173, we apply the division lemma to 497 and 173, to get
497 = 173 x 2 + 151
Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 151 and 173, to get
173 = 151 x 1 + 22
Step 3: We consider the new divisor 151 and the new remainder 22, and apply the division lemma to get
151 = 22 x 6 + 19
We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get
22 = 19 x 1 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 497 and 173 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(151,22) = HCF(173,151) = HCF(497,173) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 830 > 1, we apply the division lemma to 830 and 1, to get
830 = 1 x 830 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 830 is 1
Notice that 1 = HCF(830,1) .
