HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 730, 788, 478 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 730, 788, 478 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 670, 730, 788, 478 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 670, 730, 788, 478 is 2.
HCF(670, 730, 788, 478) = 2
HCF of 670, 730, 788, 478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 730, 788, 478 is 2.
Highest Common Factor of 670,730,788,478 is 2
Step 1: Since 730 > 670, we apply the division lemma to 730 and 670, to get
730 = 670 x 1 + 60
Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 60 and 670, to get
670 = 60 x 11 + 10
Step 3: We consider the new divisor 60 and the new remainder 10, and apply the division lemma to get
60 = 10 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 670 and 730 is 10
Notice that 10 = HCF(60,10) = HCF(670,60) = HCF(730,670) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 788 > 10, we apply the division lemma to 788 and 10, to get
788 = 10 x 78 + 8
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get
10 = 8 x 1 + 2
Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 788 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(788,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 2, we apply the division lemma to 478 and 2, to get
478 = 2 x 239 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 478 is 2
Notice that 2 = HCF(478,2) .
