HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 2381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 802, 2381 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 802, 2381 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 802, 2381 is 1.
HCF(802, 2381) = 1
HCF of 802, 2381 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 802, 2381 is 1.
Highest Common Factor of 802,2381 is 1
Step 1: Since 2381 > 802, we apply the division lemma to 2381 and 802, to get
2381 = 802 x 2 + 777
Step 2: Since the reminder 802 ≠ 0, we apply division lemma to 777 and 802, to get
802 = 777 x 1 + 25
Step 3: We consider the new divisor 777 and the new remainder 25, and apply the division lemma to get
777 = 25 x 31 + 2
We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get
25 = 2 x 12 + 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 802 and 2381 is 1
Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(777,25) = HCF(802,777) = HCF(2381,802) .
