HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 860, 969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 381, 860, 969 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, 860, 969 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, 860, 969 is 1.
HCF(381, 860, 969) = 1
HCF of 381, 860, 969 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, 860, 969 is 1.
Highest Common Factor of 381,860,969 is 1
Step 1: Since 860 > 381, we apply the division lemma to 860 and 381, to get
860 = 381 x 2 + 98
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 98 and 381, to get
381 = 98 x 3 + 87
Step 3: We consider the new divisor 98 and the new remainder 87, and apply the division lemma to get
98 = 87 x 1 + 11
We consider the new divisor 87 and the new remainder 11,and apply the division lemma to get
87 = 11 x 7 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 860 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(87,11) = HCF(98,87) = HCF(381,98) = HCF(860,381) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 969 > 1, we apply the division lemma to 969 and 1, to get
969 = 1 x 969 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 969 is 1
Notice that 1 = HCF(969,1) .
