HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 911 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 911 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, 911 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, 911 is 1.
HCF(689, 911) = 1
HCF of 689, 911 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, 911 is 1.
Highest Common Factor of 689,911 is 1
Step 1: Since 911 > 689, we apply the division lemma to 911 and 689, to get
911 = 689 x 1 + 222
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 222 and 689, to get
689 = 222 x 3 + 23
Step 3: We consider the new divisor 222 and the new remainder 23, and apply the division lemma to get
222 = 23 x 9 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 689 and 911 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(222,23) = HCF(689,222) = HCF(911,689) .
