HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 790, 752 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 790, 752 is 2 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 472, 790, 752 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 472, 790, 752 is 2.
HCF(472, 790, 752) = 2
HCF of 472, 790, 752 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 790, 752 is 2.
Highest Common Factor of 472,790,752 is 2
Step 1: Since 790 > 472, we apply the division lemma to 790 and 472, to get
790 = 472 x 1 + 318
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 318 and 472, to get
472 = 318 x 1 + 154
Step 3: We consider the new divisor 318 and the new remainder 154, and apply the division lemma to get
318 = 154 x 2 + 10
We consider the new divisor 154 and the new remainder 10,and apply the division lemma to get
154 = 10 x 15 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 472 and 790 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(154,10) = HCF(318,154) = HCF(472,318) = HCF(790,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 752 > 2, we apply the division lemma to 752 and 2, to get
752 = 2 x 376 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 752 is 2
Notice that 2 = HCF(752,2) .
