HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 977, 607, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 977, 607, 77 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 628, 977, 607, 77 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 628, 977, 607, 77 is 1.
HCF(628, 977, 607, 77) = 1
HCF of 628, 977, 607, 77 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 628, 977, 607, 77 is 1.
Highest Common Factor of 628,977,607,77 is 1
Step 1: Since 977 > 628, we apply the division lemma to 977 and 628, to get
977 = 628 x 1 + 349
Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 349 and 628, to get
628 = 349 x 1 + 279
Step 3: We consider the new divisor 349 and the new remainder 279, and apply the division lemma to get
349 = 279 x 1 + 70
We consider the new divisor 279 and the new remainder 70,and apply the division lemma to get
279 = 70 x 3 + 69
We consider the new divisor 70 and the new remainder 69,and apply the division lemma to get
70 = 69 x 1 + 1
We consider the new divisor 69 and the new remainder 1,and apply the division lemma to get
69 = 1 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 628 and 977 is 1
Notice that 1 = HCF(69,1) = HCF(70,69) = HCF(279,70) = HCF(349,279) = HCF(628,349) = HCF(977,628) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 607 > 1, we apply the division lemma to 607 and 1, to get
607 = 1 x 607 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 607 is 1
Notice that 1 = HCF(607,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1
Notice that 1 = HCF(77,1) .
