HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 757, 770, 315 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 423, 757, 770, 315 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 423, 757, 770, 315 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 423, 757, 770, 315 is 1.

HCF(423, 757, 770, 315) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 423, 757, 770, 315 is 1.

Highest Common Factor of 423,757,770,315 using Euclid's algorithm

Highest Common Factor of 423,757,770,315 is 1

Step 1: Since 757 > 423, we apply the division lemma to 757 and 423, to get

757 = 423 x 1 + 334

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 334 and 423, to get

423 = 334 x 1 + 89

Step 3: We consider the new divisor 334 and the new remainder 89, and apply the division lemma to get

334 = 89 x 3 + 67

We consider the new divisor 89 and the new remainder 67,and apply the division lemma to get

89 = 67 x 1 + 22

We consider the new divisor 67 and the new remainder 22,and apply the division lemma to get

67 = 22 x 3 + 1

We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get

22 = 1 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 423 and 757 is 1

Notice that 1 = HCF(22,1) = HCF(67,22) = HCF(89,67) = HCF(334,89) = HCF(423,334) = HCF(757,423) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 770 > 1, we apply the division lemma to 770 and 1, to get

770 = 1 x 770 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 770 is 1

Notice that 1 = HCF(770,1) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 315 > 1, we apply the division lemma to 315 and 1, to get

315 = 1 x 315 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 315 is 1

Notice that 1 = HCF(315,1) .
