HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 782, 722 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 315, 782, 722 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 315, 782, 722 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 315, 782, 722 is 1.

HCF(315, 782, 722) = 1

Highest common factor (HCF) of 315, 782, 722 is 1.

Highest Common Factor of 315,782,722 using Euclid's algorithm

Highest Common Factor of 315,782,722 is 1

Step 1: Since 782 > 315, we apply the division lemma to 782 and 315, to get

782 = 315 x 2 + 152

Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 152 and 315, to get

315 = 152 x 2 + 11

Step 3: We consider the new divisor 152 and the new remainder 11, and apply the division lemma to get

152 = 11 x 13 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 315 and 782 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(152,11) = HCF(315,152) = HCF(782,315) .

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

Step 1: Since 722 > 1, we apply the division lemma to 722 and 1, to get

722 = 1 x 722 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 722 is 1

Notice that 1 = HCF(722,1) .
