HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 799, 21218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 799, 21218 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 799, 21218 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 799, 21218 is 1.
HCF(799, 21218) = 1
HCF of 799, 21218 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 799, 21218 is 1.
Highest Common Factor of 799,21218 is 1
Step 1: Since 21218 > 799, we apply the division lemma to 21218 and 799, to get
21218 = 799 x 26 + 444
Step 2: Since the reminder 799 ≠ 0, we apply division lemma to 444 and 799, to get
799 = 444 x 1 + 355
Step 3: We consider the new divisor 444 and the new remainder 355, and apply the division lemma to get
444 = 355 x 1 + 89
We consider the new divisor 355 and the new remainder 89,and apply the division lemma to get
355 = 89 x 3 + 88
We consider the new divisor 89 and the new remainder 88,and apply the division lemma to get
89 = 88 x 1 + 1
We consider the new divisor 88 and the new remainder 1,and apply the division lemma to get
88 = 1 x 88 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 799 and 21218 is 1
Notice that 1 = HCF(88,1) = HCF(89,88) = HCF(355,89) = HCF(444,355) = HCF(799,444) = HCF(21218,799) .
