HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 264, 435, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 264, 435, 787 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 264, 435, 787 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 264, 435, 787 is 1.

HCF(264, 435, 787) = 1

Highest common factor (HCF) of 264, 435, 787 is 1.

Highest Common Factor of 264,435,787 using Euclid's algorithm

Highest Common Factor of 264,435,787 is 1

Step 1: Since 435 > 264, we apply the division lemma to 435 and 264, to get

435 = 264 x 1 + 171

Step 2: Since the reminder 264 ≠ 0, we apply division lemma to 171 and 264, to get

264 = 171 x 1 + 93

Step 3: We consider the new divisor 171 and the new remainder 93, and apply the division lemma to get

171 = 93 x 1 + 78

We consider the new divisor 93 and the new remainder 78,and apply the division lemma to get

93 = 78 x 1 + 15

We consider the new divisor 78 and the new remainder 15,and apply the division lemma to get

78 = 15 x 5 + 3

We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 264 and 435 is 3

Notice that 3 = HCF(15,3) = HCF(78,15) = HCF(93,78) = HCF(171,93) = HCF(264,171) = HCF(435,264) .

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

Step 1: Since 787 > 3, we apply the division lemma to 787 and 3, to get

787 = 3 x 262 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 787 is 1

Notice that 1 = HCF(3,1) = HCF(787,3) .
