HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 875, 561 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 875, 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 875, 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 875, 561 is 1.
HCF(875, 561) = 1
HCF of 875, 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 875, 561 is 1.
Highest Common Factor of 875,561 is 1
Step 1: Since 875 > 561, we apply the division lemma to 875 and 561, to get
875 = 561 x 1 + 314
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 314 and 561, to get
561 = 314 x 1 + 247
Step 3: We consider the new divisor 314 and the new remainder 247, and apply the division lemma to get
314 = 247 x 1 + 67
We consider the new divisor 247 and the new remainder 67,and apply the division lemma to get
247 = 67 x 3 + 46
We consider the new divisor 67 and the new remainder 46,and apply the division lemma to get
67 = 46 x 1 + 21
We consider the new divisor 46 and the new remainder 21,and apply the division lemma to get
46 = 21 x 2 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 875 and 561 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(46,21) = HCF(67,46) = HCF(247,67) = HCF(314,247) = HCF(561,314) = HCF(875,561) .
