HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 597, 20 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 597, 20 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 407, 597, 20 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 407, 597, 20 is 1.
HCF(407, 597, 20) = 1
HCF of 407, 597, 20 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 407, 597, 20 is 1.
Highest Common Factor of 407,597,20 is 1
Step 1: Since 597 > 407, we apply the division lemma to 597 and 407, to get
597 = 407 x 1 + 190
Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 190 and 407, to get
407 = 190 x 2 + 27
Step 3: We consider the new divisor 190 and the new remainder 27, and apply the division lemma to get
190 = 27 x 7 + 1
We consider the new divisor 27 and the new remainder 1, and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 407 and 597 is 1
Notice that 1 = HCF(27,1) = HCF(190,27) = HCF(407,190) = HCF(597,407) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 1, we apply the division lemma to 20 and 1, to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 20 is 1
Notice that 1 = HCF(20,1) .
