HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 502, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 502, 855 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 502, 855 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 502, 855 is 1.
HCF(502, 855) = 1
HCF of 502, 855 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 502, 855 is 1.
Highest Common Factor of 502,855 is 1
Step 1: Since 855 > 502, we apply the division lemma to 855 and 502, to get
855 = 502 x 1 + 353
Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 353 and 502, to get
502 = 353 x 1 + 149
Step 3: We consider the new divisor 353 and the new remainder 149, and apply the division lemma to get
353 = 149 x 2 + 55
We consider the new divisor 149 and the new remainder 55,and apply the division lemma to get
149 = 55 x 2 + 39
We consider the new divisor 55 and the new remainder 39,and apply the division lemma to get
55 = 39 x 1 + 16
We consider the new divisor 39 and the new remainder 16,and apply the division lemma to get
39 = 16 x 2 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 502 and 855 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(39,16) = HCF(55,39) = HCF(149,55) = HCF(353,149) = HCF(502,353) = HCF(855,502) .
