HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 356, 584, 640 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 977, 356, 584, 640 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 977, 356, 584, 640 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 977, 356, 584, 640 is 1.

HCF(977, 356, 584, 640) = 1

Highest Common Factor of 977,356,584,640 using Euclid's algorithm

Highest Common Factor of 977,356,584,640 is 1

Step 1: Since 977 > 356, we apply the division lemma to 977 and 356, to get

977 = 356 x 2 + 265

Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 265 and 356, to get

356 = 265 x 1 + 91

Step 3: We consider the new divisor 265 and the new remainder 91, and apply the division lemma to get

265 = 91 x 2 + 83

We consider the new divisor 91 and the new remainder 83,and apply the division lemma to get

91 = 83 x 1 + 8

We consider the new divisor 83 and the new remainder 8,and apply the division lemma to get

83 = 8 x 10 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 2

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

3 = 2 x 1 + 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 977 and 356 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(83,8) = HCF(91,83) = HCF(265,91) = HCF(356,265) = HCF(977,356) .


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

Step 1: Since 584 > 1, we apply the division lemma to 584 and 1, to get

584 = 1 x 584 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 584 is 1

Notice that 1 = HCF(584,1) .


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

Step 1: Since 640 > 1, we apply the division lemma to 640 and 1, to get

640 = 1 x 640 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 640 is 1

Notice that 1 = HCF(640,1) .
