HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 877, 634, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 877, 634, 654 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 877, 634, 654 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 877, 634, 654 is 1.
HCF(877, 634, 654) = 1
HCF of 877, 634, 654 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 877, 634, 654 is 1.
Highest Common Factor of 877,634,654 is 1
Step 1: Since 877 > 634, we apply the division lemma to 877 and 634, to get
877 = 634 x 1 + 243
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 243 and 634, to get
634 = 243 x 2 + 148
Step 3: We consider the new divisor 243 and the new remainder 148, and apply the division lemma to get
243 = 148 x 1 + 95
We consider the new divisor 148 and the new remainder 95,and apply the division lemma to get
148 = 95 x 1 + 53
We consider the new divisor 95 and the new remainder 53,and apply the division lemma to get
95 = 53 x 1 + 42
We consider the new divisor 53 and the new remainder 42,and apply the division lemma to get
53 = 42 x 1 + 11
We consider the new divisor 42 and the new remainder 11,and apply the division lemma to get
42 = 11 x 3 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 877 and 634 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(42,11) = HCF(53,42) = HCF(95,53) = HCF(148,95) = HCF(243,148) = HCF(634,243) = HCF(877,634) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get
654 = 1 x 654 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1
Notice that 1 = HCF(654,1) .
