HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 973, 561 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 973, 561 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 973, 561 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 973, 561 is 1.
HCF(973, 561) = 1
HCF of 973, 561 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 973, 561 is 1.
Highest Common Factor of 973,561 is 1
Step 1: Since 973 > 561, we apply the division lemma to 973 and 561, to get
973 = 561 x 1 + 412
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 412 and 561, to get
561 = 412 x 1 + 149
Step 3: We consider the new divisor 412 and the new remainder 149, and apply the division lemma to get
412 = 149 x 2 + 114
We consider the new divisor 149 and the new remainder 114,and apply the division lemma to get
149 = 114 x 1 + 35
We consider the new divisor 114 and the new remainder 35,and apply the division lemma to get
114 = 35 x 3 + 9
We consider the new divisor 35 and the new remainder 9,and apply the division lemma to get
35 = 9 x 3 + 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 973 and 561 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(35,9) = HCF(114,35) = HCF(149,114) = HCF(412,149) = HCF(561,412) = HCF(973,561) .
