HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 93, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 93, 639 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 56, 93, 639 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 56, 93, 639 is 1.
HCF(56, 93, 639) = 1
HCF of 56, 93, 639 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 56, 93, 639 is 1.
Highest Common Factor of 56,93,639 is 1
Step 1: Since 93 > 56, we apply the division lemma to 93 and 56, to get
93 = 56 x 1 + 37
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 37 and 56, to get
56 = 37 x 1 + 19
Step 3: We consider the new divisor 37 and the new remainder 19, and apply the division lemma to get
37 = 19 x 1 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 56 and 93 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(37,19) = HCF(56,37) = HCF(93,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 639 > 1, we apply the division lemma to 639 and 1, to get
639 = 1 x 639 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 639 is 1
Notice that 1 = HCF(639,1) .
