HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 790, 435, 29 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 790, 435, 29 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 785, 790, 435, 29 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 785, 790, 435, 29 is 1.
HCF(785, 790, 435, 29) = 1
HCF of 785, 790, 435, 29 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 790, 435, 29 is 1.
Highest Common Factor of 785,790,435,29 is 1
Step 1: Since 790 > 785, we apply the division lemma to 790 and 785, to get
790 = 785 x 1 + 5
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 5 and 785, to get
785 = 5 x 157 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 785 and 790 is 5
Notice that 5 = HCF(785,5) = HCF(790,785) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 435 > 5, we apply the division lemma to 435 and 5, to get
435 = 5 x 87 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 435 is 5
Notice that 5 = HCF(435,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 29 > 5, we apply the division lemma to 29 and 5, to get
29 = 5 x 5 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: 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 5 and 29 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) .
