HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 38, 70, 708, 730 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 38, 70, 708, 730 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 38, 70, 708, 730 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 38, 70, 708, 730 is 2.
HCF(38, 70, 708, 730) = 2
HCF of 38, 70, 708, 730 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 38, 70, 708, 730 is 2.
Highest Common Factor of 38,70,708,730 is 2
Step 1: Since 70 > 38, we apply the division lemma to 70 and 38, to get
70 = 38 x 1 + 32
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 32 and 38, to get
38 = 32 x 1 + 6
Step 3: We consider the new divisor 32 and the new remainder 6, and apply the division lemma to get
32 = 6 x 5 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 38 and 70 is 2
Notice that 2 = HCF(6,2) = HCF(32,6) = HCF(38,32) = HCF(70,38) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 708 > 2, we apply the division lemma to 708 and 2, to get
708 = 2 x 354 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 708 is 2
Notice that 2 = HCF(708,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 730 > 2, we apply the division lemma to 730 and 2, to get
730 = 2 x 365 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 730 is 2
Notice that 2 = HCF(730,2) .
