HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 491, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 491, 386 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 870, 491, 386 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 870, 491, 386 is 1.
HCF(870, 491, 386) = 1
HCF of 870, 491, 386 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 491, 386 is 1.
Highest Common Factor of 870,491,386 is 1
Step 1: Since 870 > 491, we apply the division lemma to 870 and 491, to get
870 = 491 x 1 + 379
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 379 and 491, to get
491 = 379 x 1 + 112
Step 3: We consider the new divisor 379 and the new remainder 112, and apply the division lemma to get
379 = 112 x 3 + 43
We consider the new divisor 112 and the new remainder 43,and apply the division lemma to get
112 = 43 x 2 + 26
We consider the new divisor 43 and the new remainder 26,and apply the division lemma to get
43 = 26 x 1 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 870 and 491 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(43,26) = HCF(112,43) = HCF(379,112) = HCF(491,379) = HCF(870,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get
386 = 1 x 386 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1
Notice that 1 = HCF(386,1) .
