HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 841, 720, 427 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 784, 841, 720, 427 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 784, 841, 720, 427 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 784, 841, 720, 427 is 1.

HCF(784, 841, 720, 427) = 1

Highest common factor (HCF) of 784, 841, 720, 427 is 1.

Highest Common Factor of 784,841,720,427 using Euclid's algorithm

Highest Common Factor of 784,841,720,427 is 1

Step 1: Since 841 > 784, we apply the division lemma to 841 and 784, to get

841 = 784 x 1 + 57

Step 2: Since the reminder 784 ≠ 0, we apply division lemma to 57 and 784, to get

784 = 57 x 13 + 43

Step 3: We consider the new divisor 57 and the new remainder 43, and apply the division lemma to get

57 = 43 x 1 + 14

We consider the new divisor 43 and the new remainder 14,and apply the division lemma to get

43 = 14 x 3 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 784 and 841 is 1

Notice that 1 = HCF(14,1) = HCF(43,14) = HCF(57,43) = HCF(784,57) = HCF(841,784) .


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

Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get

720 = 1 x 720 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1

Notice that 1 = HCF(720,1) .


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

Step 1: Since 427 > 1, we apply the division lemma to 427 and 1, to get

427 = 1 x 427 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 427 is 1

Notice that 1 = HCF(427,1) .
