HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 523, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 523, 287 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 523, 287 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 523, 287 is 1.
HCF(523, 287) = 1
HCF of 523, 287 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 523, 287 is 1.
Highest Common Factor of 523,287 is 1
Step 1: Since 523 > 287, we apply the division lemma to 523 and 287, to get
523 = 287 x 1 + 236
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 236 and 287, to get
287 = 236 x 1 + 51
Step 3: We consider the new divisor 236 and the new remainder 51, and apply the division lemma to get
236 = 51 x 4 + 32
We consider the new divisor 51 and the new remainder 32,and apply the division lemma to get
51 = 32 x 1 + 19
We consider the new divisor 32 and the new remainder 19,and apply the division lemma to get
32 = 19 x 1 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 523 and 287 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(51,32) = HCF(236,51) = HCF(287,236) = HCF(523,287) .
