HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 634, 658, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 634, 658, 657 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 494, 634, 658, 657 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 494, 634, 658, 657 is 1.
HCF(494, 634, 658, 657) = 1
HCF of 494, 634, 658, 657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 634, 658, 657 is 1.
Highest Common Factor of 494,634,658,657 is 1
Step 1: Since 634 > 494, we apply the division lemma to 634 and 494, to get
634 = 494 x 1 + 140
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 140 and 494, to get
494 = 140 x 3 + 74
Step 3: We consider the new divisor 140 and the new remainder 74, and apply the division lemma to get
140 = 74 x 1 + 66
We consider the new divisor 74 and the new remainder 66,and apply the division lemma to get
74 = 66 x 1 + 8
We consider the new divisor 66 and the new remainder 8,and apply the division lemma to get
66 = 8 x 8 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 494 and 634 is 2
Notice that 2 = HCF(8,2) = HCF(66,8) = HCF(74,66) = HCF(140,74) = HCF(494,140) = HCF(634,494) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 658 > 2, we apply the division lemma to 658 and 2, to get
658 = 2 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 658 is 2
Notice that 2 = HCF(658,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 2, we apply the division lemma to 657 and 2, to get
657 = 2 x 328 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 657 is 1
Notice that 1 = HCF(2,1) = HCF(657,2) .
