HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 577, 673, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 577, 673, 76 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 998, 577, 673, 76 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 998, 577, 673, 76 is 1.
HCF(998, 577, 673, 76) = 1
HCF of 998, 577, 673, 76 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 998, 577, 673, 76 is 1.
Highest Common Factor of 998,577,673,76 is 1
Step 1: Since 998 > 577, we apply the division lemma to 998 and 577, to get
998 = 577 x 1 + 421
Step 2: Since the reminder 577 ≠ 0, we apply division lemma to 421 and 577, to get
577 = 421 x 1 + 156
Step 3: We consider the new divisor 421 and the new remainder 156, and apply the division lemma to get
421 = 156 x 2 + 109
We consider the new divisor 156 and the new remainder 109,and apply the division lemma to get
156 = 109 x 1 + 47
We consider the new divisor 109 and the new remainder 47,and apply the division lemma to get
109 = 47 x 2 + 15
We consider the new divisor 47 and the new remainder 15,and apply the division lemma to get
47 = 15 x 3 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 998 and 577 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(47,15) = HCF(109,47) = HCF(156,109) = HCF(421,156) = HCF(577,421) = HCF(998,577) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 673 > 1, we apply the division lemma to 673 and 1, to get
673 = 1 x 673 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 673 is 1
Notice that 1 = HCF(673,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 1, we apply the division lemma to 76 and 1, to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76 is 1
Notice that 1 = HCF(76,1) .
