HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 808, 980 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 808, 980 is 4 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 808, 980 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 808, 980 is 4.
HCF(808, 980) = 4
HCF of 808, 980 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 808, 980 is 4.
Highest Common Factor of 808,980 is 4
Step 1: Since 980 > 808, we apply the division lemma to 980 and 808, to get
980 = 808 x 1 + 172
Step 2: Since the reminder 808 ≠ 0, we apply division lemma to 172 and 808, to get
808 = 172 x 4 + 120
Step 3: We consider the new divisor 172 and the new remainder 120, and apply the division lemma to get
172 = 120 x 1 + 52
We consider the new divisor 120 and the new remainder 52,and apply the division lemma to get
120 = 52 x 2 + 16
We consider the new divisor 52 and the new remainder 16,and apply the division lemma to get
52 = 16 x 3 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 808 and 980 is 4
Notice that 4 = HCF(16,4) = HCF(52,16) = HCF(120,52) = HCF(172,120) = HCF(808,172) = HCF(980,808) .
