HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 170, 527 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 170, 527 is 17 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 816, 170, 527 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 816, 170, 527 is 17.
HCF(816, 170, 527) = 17
HCF of 816, 170, 527 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 170, 527 is 17.
Highest Common Factor of 816,170,527 is 17
Step 1: Since 816 > 170, we apply the division lemma to 816 and 170, to get
816 = 170 x 4 + 136
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 136 and 170, to get
170 = 136 x 1 + 34
Step 3: We consider the new divisor 136 and the new remainder 34, and apply the division lemma to get
136 = 34 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 816 and 170 is 34
Notice that 34 = HCF(136,34) = HCF(170,136) = HCF(816,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 527 > 34, we apply the division lemma to 527 and 34, to get
527 = 34 x 15 + 17
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 17 and 34, to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 34 and 527 is 17
Notice that 17 = HCF(34,17) = HCF(527,34) .
