HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 920 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 381, 920 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 381, 920 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 381, 920 is 1.
HCF(381, 920) = 1
HCF of 381, 920 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 381, 920 is 1.
Highest Common Factor of 381,920 is 1
Step 1: Since 920 > 381, we apply the division lemma to 920 and 381, to get
920 = 381 x 2 + 158
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 158 and 381, to get
381 = 158 x 2 + 65
Step 3: We consider the new divisor 158 and the new remainder 65, and apply the division lemma to get
158 = 65 x 2 + 28
We consider the new divisor 65 and the new remainder 28,and apply the division lemma to get
65 = 28 x 2 + 9
We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get
28 = 9 x 3 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 920 is 1
Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(65,28) = HCF(158,65) = HCF(381,158) = HCF(920,381) .
