HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 683, 87987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 683, 87987 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 683, 87987 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 683, 87987 is 1.
HCF(683, 87987) = 1
HCF of 683, 87987 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 683, 87987 is 1.
Highest Common Factor of 683,87987 is 1
Step 1: Since 87987 > 683, we apply the division lemma to 87987 and 683, to get
87987 = 683 x 128 + 563
Step 2: Since the reminder 683 ≠ 0, we apply division lemma to 563 and 683, to get
683 = 563 x 1 + 120
Step 3: We consider the new divisor 563 and the new remainder 120, and apply the division lemma to get
563 = 120 x 4 + 83
We consider the new divisor 120 and the new remainder 83,and apply the division lemma to get
120 = 83 x 1 + 37
We consider the new divisor 83 and the new remainder 37,and apply the division lemma to get
83 = 37 x 2 + 9
We consider the new divisor 37 and the new remainder 9,and apply the division lemma to get
37 = 9 x 4 + 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 683 and 87987 is 1
Notice that 1 = HCF(9,1) = HCF(37,9) = HCF(83,37) = HCF(120,83) = HCF(563,120) = HCF(683,563) = HCF(87987,683) .
