HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 61, 661, 613, 940 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 61, 661, 613, 940 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 61, 661, 613, 940 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 61, 661, 613, 940 is 1.
HCF(61, 661, 613, 940) = 1
HCF of 61, 661, 613, 940 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 61, 661, 613, 940 is 1.
Highest Common Factor of 61,661,613,940 is 1
Step 1: Since 661 > 61, we apply the division lemma to 661 and 61, to get
661 = 61 x 10 + 51
Step 2: Since the reminder 61 ≠ 0, we apply division lemma to 51 and 61, to get
61 = 51 x 1 + 10
Step 3: We consider the new divisor 51 and the new remainder 10, and apply the division lemma to get
51 = 10 x 5 + 1
We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 61 and 661 is 1
Notice that 1 = HCF(10,1) = HCF(51,10) = HCF(61,51) = HCF(661,61) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 613 > 1, we apply the division lemma to 613 and 1, to get
613 = 1 x 613 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 613 is 1
Notice that 1 = HCF(613,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 940 > 1, we apply the division lemma to 940 and 1, to get
940 = 1 x 940 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 940 is 1
Notice that 1 = HCF(940,1) .
