HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 87 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 653, 87 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 653, 87 is 1.
HCF(653, 87) = 1
HCF of 653, 87 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 87 is 1.
Highest Common Factor of 653,87 is 1
Step 1: Since 653 > 87, we apply the division lemma to 653 and 87, to get
653 = 87 x 7 + 44
Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 44 and 87, to get
87 = 44 x 1 + 43
Step 3: We consider the new divisor 44 and the new remainder 43, and apply the division lemma to get
44 = 43 x 1 + 1
We consider the new divisor 43 and the new remainder 1, and apply the division lemma to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 653 and 87 is 1
Notice that 1 = HCF(43,1) = HCF(44,43) = HCF(87,44) = HCF(653,87) .
