HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 941, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 681, 941, 973 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 681, 941, 973 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 681, 941, 973 is 1.
HCF(681, 941, 973) = 1
HCF of 681, 941, 973 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 681, 941, 973 is 1.
Highest Common Factor of 681,941,973 is 1
Step 1: Since 941 > 681, we apply the division lemma to 941 and 681, to get
941 = 681 x 1 + 260
Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 260 and 681, to get
681 = 260 x 2 + 161
Step 3: We consider the new divisor 260 and the new remainder 161, and apply the division lemma to get
260 = 161 x 1 + 99
We consider the new divisor 161 and the new remainder 99,and apply the division lemma to get
161 = 99 x 1 + 62
We consider the new divisor 99 and the new remainder 62,and apply the division lemma to get
99 = 62 x 1 + 37
We consider the new divisor 62 and the new remainder 37,and apply the division lemma to get
62 = 37 x 1 + 25
We consider the new divisor 37 and the new remainder 25,and apply the division lemma to get
37 = 25 x 1 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 681 and 941 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(37,25) = HCF(62,37) = HCF(99,62) = HCF(161,99) = HCF(260,161) = HCF(681,260) = HCF(941,681) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 1, we apply the division lemma to 973 and 1, to get
973 = 1 x 973 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 973 is 1
Notice that 1 = HCF(973,1) .
