HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 735, 40 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 735, 40 is 5 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 400, 735, 40 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 400, 735, 40 is 5.
HCF(400, 735, 40) = 5
HCF of 400, 735, 40 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 735, 40 is 5.
Highest Common Factor of 400,735,40 is 5
Step 1: Since 735 > 400, we apply the division lemma to 735 and 400, to get
735 = 400 x 1 + 335
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 335 and 400, to get
400 = 335 x 1 + 65
Step 3: We consider the new divisor 335 and the new remainder 65, and apply the division lemma to get
335 = 65 x 5 + 10
We consider the new divisor 65 and the new remainder 10,and apply the division lemma to get
65 = 10 x 6 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 400 and 735 is 5
Notice that 5 = HCF(10,5) = HCF(65,10) = HCF(335,65) = HCF(400,335) = HCF(735,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 5, we apply the division lemma to 40 and 5, to get
40 = 5 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 40 is 5
Notice that 5 = HCF(40,5) .
