HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 709, 320 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 709, 320 is 1 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 425, 709, 320 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 425, 709, 320 is 1.
HCF(425, 709, 320) = 1
HCF of 425, 709, 320 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 709, 320 is 1.
Highest Common Factor of 425,709,320 is 1
Step 1: Since 709 > 425, we apply the division lemma to 709 and 425, to get
709 = 425 x 1 + 284
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 284 and 425, to get
425 = 284 x 1 + 141
Step 3: We consider the new divisor 284 and the new remainder 141, and apply the division lemma to get
284 = 141 x 2 + 2
We consider the new divisor 141 and the new remainder 2,and apply the division lemma to get
141 = 2 x 70 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 425 and 709 is 1
Notice that 1 = HCF(2,1) = HCF(141,2) = HCF(284,141) = HCF(425,284) = HCF(709,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 320 > 1, we apply the division lemma to 320 and 1, to get
320 = 1 x 320 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 320 is 1
Notice that 1 = HCF(320,1) .
