HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 945 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 782, 945 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 782, 945 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 782, 945 is 1.

HCF(782, 945) = 1

Highest common factor (HCF) of 782, 945 is 1.

Highest Common Factor of 782,945 using Euclid's algorithm

Highest Common Factor of 782,945 is 1

Step 1: Since 945 > 782, we apply the division lemma to 945 and 782, to get

945 = 782 x 1 + 163

Step 2: Since the reminder 782 ≠ 0, we apply division lemma to 163 and 782, to get

782 = 163 x 4 + 130

Step 3: We consider the new divisor 163 and the new remainder 130, and apply the division lemma to get

163 = 130 x 1 + 33

We consider the new divisor 130 and the new remainder 33,and apply the division lemma to get

130 = 33 x 3 + 31

We consider the new divisor 33 and the new remainder 31,and apply the division lemma to get

33 = 31 x 1 + 2

We consider the new divisor 31 and the new remainder 2,and apply the division lemma to get

31 = 2 x 15 + 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 782 and 945 is 1

Notice that 1 = HCF(2,1) = HCF(31,2) = HCF(33,31) = HCF(130,33) = HCF(163,130) = HCF(782,163) = HCF(945,782) .
