HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 561 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 561 is 3 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 240, 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 240, 561 is 3.
HCF(240, 561) = 3
HCF of 240, 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 240, 561 is 3.
Highest Common Factor of 240,561 is 3
Step 1: Since 561 > 240, we apply the division lemma to 561 and 240, to get
561 = 240 x 2 + 81
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 81 and 240, to get
240 = 81 x 2 + 78
Step 3: We consider the new divisor 81 and the new remainder 78, and apply the division lemma to get
81 = 78 x 1 + 3
We consider the new divisor 78 and the new remainder 3, and apply the division lemma to get
78 = 3 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 240 and 561 is 3
Notice that 3 = HCF(78,3) = HCF(81,78) = HCF(240,81) = HCF(561,240) .
