HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 522, 287, 672, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 522, 287, 672, 639 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 522, 287, 672, 639 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 522, 287, 672, 639 is 1.

HCF(522, 287, 672, 639) = 1

Highest Common Factor of 522,287,672,639 using Euclid's algorithm

Highest Common Factor of 522,287,672,639 is 1

Step 1: Since 522 > 287, we apply the division lemma to 522 and 287, to get

522 = 287 x 1 + 235

Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 235 and 287, to get

287 = 235 x 1 + 52

Step 3: We consider the new divisor 235 and the new remainder 52, and apply the division lemma to get

235 = 52 x 4 + 27

We consider the new divisor 52 and the new remainder 27,and apply the division lemma to get

52 = 27 x 1 + 25

We consider the new divisor 27 and the new remainder 25,and apply the division lemma to get

27 = 25 x 1 + 2

We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get

25 = 2 x 12 + 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 522 and 287 is 1

Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(27,25) = HCF(52,27) = HCF(235,52) = HCF(287,235) = HCF(522,287) .

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

Step 1: Since 672 > 1, we apply the division lemma to 672 and 1, to get

672 = 1 x 672 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 672 is 1

Notice that 1 = HCF(672,1) .

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

Step 1: Since 639 > 1, we apply the division lemma to 639 and 1, to get

639 = 1 x 639 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 639 is 1

Notice that 1 = HCF(639,1) .
