HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 709, 665, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 402, 709, 665, 253 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 402, 709, 665, 253 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 402, 709, 665, 253 is 1.
HCF(402, 709, 665, 253) = 1
HCF of 402, 709, 665, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 402, 709, 665, 253 is 1.
Highest Common Factor of 402,709,665,253 is 1
Step 1: Since 709 > 402, we apply the division lemma to 709 and 402, to get
709 = 402 x 1 + 307
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 307 and 402, to get
402 = 307 x 1 + 95
Step 3: We consider the new divisor 307 and the new remainder 95, and apply the division lemma to get
307 = 95 x 3 + 22
We consider the new divisor 95 and the new remainder 22,and apply the division lemma to get
95 = 22 x 4 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 402 and 709 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(95,22) = HCF(307,95) = HCF(402,307) = HCF(709,402) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 665 > 1, we apply the division lemma to 665 and 1, to get
665 = 1 x 665 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 665 is 1
Notice that 1 = HCF(665,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 253 > 1, we apply the division lemma to 253 and 1, to get
253 = 1 x 253 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 253 is 1
Notice that 1 = HCF(253,1) .
