HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 392, 730, 634, 982 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 392, 730, 634, 982 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 392, 730, 634, 982 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 392, 730, 634, 982 is 2.
HCF(392, 730, 634, 982) = 2
HCF of 392, 730, 634, 982 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 392, 730, 634, 982 is 2.
Highest Common Factor of 392,730,634,982 is 2
Step 1: Since 730 > 392, we apply the division lemma to 730 and 392, to get
730 = 392 x 1 + 338
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 338 and 392, to get
392 = 338 x 1 + 54
Step 3: We consider the new divisor 338 and the new remainder 54, and apply the division lemma to get
338 = 54 x 6 + 14
We consider the new divisor 54 and the new remainder 14,and apply the division lemma to get
54 = 14 x 3 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 392 and 730 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(54,14) = HCF(338,54) = HCF(392,338) = HCF(730,392) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 634 > 2, we apply the division lemma to 634 and 2, to get
634 = 2 x 317 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 634 is 2
Notice that 2 = HCF(634,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 982 > 2, we apply the division lemma to 982 and 2, to get
982 = 2 x 491 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 982 is 2
Notice that 2 = HCF(982,2) .
