HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 385, 639, 676 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 385, 639, 676 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 385, 639, 676 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 385, 639, 676 is 1.
HCF(385, 639, 676) = 1
HCF of 385, 639, 676 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 385, 639, 676 is 1.
Highest Common Factor of 385,639,676 is 1
Step 1: Since 639 > 385, we apply the division lemma to 639 and 385, to get
639 = 385 x 1 + 254
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 254 and 385, to get
385 = 254 x 1 + 131
Step 3: We consider the new divisor 254 and the new remainder 131, and apply the division lemma to get
254 = 131 x 1 + 123
We consider the new divisor 131 and the new remainder 123,and apply the division lemma to get
131 = 123 x 1 + 8
We consider the new divisor 123 and the new remainder 8,and apply the division lemma to get
123 = 8 x 15 + 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 385 and 639 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(123,8) = HCF(131,123) = HCF(254,131) = HCF(385,254) = HCF(639,385) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 676 > 1, we apply the division lemma to 676 and 1, to get
676 = 1 x 676 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 676 is 1
Notice that 1 = HCF(676,1) .
