HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 731, 569, 688, 42 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 731, 569, 688, 42 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 731, 569, 688, 42 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 731, 569, 688, 42 is 1.

HCF(731, 569, 688, 42) = 1

Highest common factor (HCF) of 731, 569, 688, 42 is 1.

Highest Common Factor of 731,569,688,42 using Euclid's algorithm

Highest Common Factor of 731,569,688,42 is 1

Step 1: Since 731 > 569, we apply the division lemma to 731 and 569, to get

731 = 569 x 1 + 162

Step 2: Since the reminder 569 ≠ 0, we apply division lemma to 162 and 569, to get

569 = 162 x 3 + 83

Step 3: We consider the new divisor 162 and the new remainder 83, and apply the division lemma to get

162 = 83 x 1 + 79

We consider the new divisor 83 and the new remainder 79,and apply the division lemma to get

83 = 79 x 1 + 4

We consider the new divisor 79 and the new remainder 4,and apply the division lemma to get

79 = 4 x 19 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 731 and 569 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(79,4) = HCF(83,79) = HCF(162,83) = HCF(569,162) = HCF(731,569) .


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

Step 1: Since 688 > 1, we apply the division lemma to 688 and 1, to get

688 = 1 x 688 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 688 is 1

Notice that 1 = HCF(688,1) .


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

Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get

42 = 1 x 42 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1

Notice that 1 = HCF(42,1) .
