HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 847, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 355, 847, 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 355, 847, 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 355, 847, 973 is 1.
HCF(355, 847, 973) = 1
HCF of 355, 847, 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 355, 847, 973 is 1.
Highest Common Factor of 355,847,973 is 1
Step 1: Since 847 > 355, we apply the division lemma to 847 and 355, to get
847 = 355 x 2 + 137
Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 137 and 355, to get
355 = 137 x 2 + 81
Step 3: We consider the new divisor 137 and the new remainder 81, and apply the division lemma to get
137 = 81 x 1 + 56
We consider the new divisor 81 and the new remainder 56,and apply the division lemma to get
81 = 56 x 1 + 25
We consider the new divisor 56 and the new remainder 25,and apply the division lemma to get
56 = 25 x 2 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 355 and 847 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(56,25) = HCF(81,56) = HCF(137,81) = HCF(355,137) = HCF(847,355) .
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) .
