HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 505, 661, 943 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 505, 661, 943 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 427, 505, 661, 943 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 427, 505, 661, 943 is 1.
HCF(427, 505, 661, 943) = 1
HCF of 427, 505, 661, 943 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 505, 661, 943 is 1.
Highest Common Factor of 427,505,661,943 is 1
Step 1: Since 505 > 427, we apply the division lemma to 505 and 427, to get
505 = 427 x 1 + 78
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 78 and 427, to get
427 = 78 x 5 + 37
Step 3: We consider the new divisor 78 and the new remainder 37, and apply the division lemma to get
78 = 37 x 2 + 4
We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get
37 = 4 x 9 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 427 and 505 is 1
Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(78,37) = HCF(427,78) = HCF(505,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 661 > 1, we apply the division lemma to 661 and 1, to get
661 = 1 x 661 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 661 is 1
Notice that 1 = HCF(661,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 943 > 1, we apply the division lemma to 943 and 1, to get
943 = 1 x 943 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 943 is 1
Notice that 1 = HCF(943,1) .
