HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 959, 871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 959, 871 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 689, 959, 871 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 689, 959, 871 is 1.
HCF(689, 959, 871) = 1
HCF of 689, 959, 871 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 689, 959, 871 is 1.
Highest Common Factor of 689,959,871 is 1
Step 1: Since 959 > 689, we apply the division lemma to 959 and 689, to get
959 = 689 x 1 + 270
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 270 and 689, to get
689 = 270 x 2 + 149
Step 3: We consider the new divisor 270 and the new remainder 149, and apply the division lemma to get
270 = 149 x 1 + 121
We consider the new divisor 149 and the new remainder 121,and apply the division lemma to get
149 = 121 x 1 + 28
We consider the new divisor 121 and the new remainder 28,and apply the division lemma to get
121 = 28 x 4 + 9
We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get
28 = 9 x 3 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 689 and 959 is 1
Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(121,28) = HCF(149,121) = HCF(270,149) = HCF(689,270) = HCF(959,689) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 871 > 1, we apply the division lemma to 871 and 1, to get
871 = 1 x 871 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 871 is 1
Notice that 1 = HCF(871,1) .
