HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 547, 923 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 851, 547, 923 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 851, 547, 923 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 851, 547, 923 is 1.
HCF(851, 547, 923) = 1
HCF of 851, 547, 923 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 851, 547, 923 is 1.
Highest Common Factor of 851,547,923 is 1
Step 1: Since 851 > 547, we apply the division lemma to 851 and 547, to get
851 = 547 x 1 + 304
Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 304 and 547, to get
547 = 304 x 1 + 243
Step 3: We consider the new divisor 304 and the new remainder 243, and apply the division lemma to get
304 = 243 x 1 + 61
We consider the new divisor 243 and the new remainder 61,and apply the division lemma to get
243 = 61 x 3 + 60
We consider the new divisor 61 and the new remainder 60,and apply the division lemma to get
61 = 60 x 1 + 1
We consider the new divisor 60 and the new remainder 1,and apply the division lemma to get
60 = 1 x 60 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 851 and 547 is 1
Notice that 1 = HCF(60,1) = HCF(61,60) = HCF(243,61) = HCF(304,243) = HCF(547,304) = HCF(851,547) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 923 > 1, we apply the division lemma to 923 and 1, to get
923 = 1 x 923 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 923 is 1
Notice that 1 = HCF(923,1) .
