HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 328, 634, 702 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 328, 634, 702 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 328, 634, 702 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 328, 634, 702 is 2.
HCF(328, 634, 702) = 2
HCF of 328, 634, 702 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 328, 634, 702 is 2.
Highest Common Factor of 328,634,702 is 2
Step 1: Since 634 > 328, we apply the division lemma to 634 and 328, to get
634 = 328 x 1 + 306
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 306 and 328, to get
328 = 306 x 1 + 22
Step 3: We consider the new divisor 306 and the new remainder 22, and apply the division lemma to get
306 = 22 x 13 + 20
We consider the new divisor 22 and the new remainder 20,and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 328 and 634 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(306,22) = HCF(328,306) = HCF(634,328) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 702 > 2, we apply the division lemma to 702 and 2, to get
702 = 2 x 351 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 702 is 2
Notice that 2 = HCF(702,2) .
