HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 690, 876, 304, 783 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 690, 876, 304, 783 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 690, 876, 304, 783 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 690, 876, 304, 783 is 1.

HCF(690, 876, 304, 783) = 1

Highest common factor (HCF) of 690, 876, 304, 783 is 1.

Highest Common Factor of 690,876,304,783 using Euclid's algorithm

Highest Common Factor of 690,876,304,783 is 1

Step 1: Since 876 > 690, we apply the division lemma to 876 and 690, to get

876 = 690 x 1 + 186

Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 186 and 690, to get

690 = 186 x 3 + 132

Step 3: We consider the new divisor 186 and the new remainder 132, and apply the division lemma to get

186 = 132 x 1 + 54

We consider the new divisor 132 and the new remainder 54,and apply the division lemma to get

132 = 54 x 2 + 24

We consider the new divisor 54 and the new remainder 24,and apply the division lemma to get

54 = 24 x 2 + 6

We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get

24 = 6 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 690 and 876 is 6

Notice that 6 = HCF(24,6) = HCF(54,24) = HCF(132,54) = HCF(186,132) = HCF(690,186) = HCF(876,690) .

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

Step 1: Since 304 > 6, we apply the division lemma to 304 and 6, to get

304 = 6 x 50 + 4

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get

6 = 4 x 1 + 2

Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 304 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(304,6) .

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

Step 1: Since 783 > 2, we apply the division lemma to 783 and 2, to get

783 = 2 x 391 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 783 is 1

Notice that 1 = HCF(2,1) = HCF(783,2) .
