HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 357, 522, 626, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 357, 522, 626, 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 357, 522, 626, 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 357, 522, 626, 77 is 1.
HCF(357, 522, 626, 77) = 1
HCF of 357, 522, 626, 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 357, 522, 626, 77 is 1.
Highest Common Factor of 357,522,626,77 is 1
Step 1: Since 522 > 357, we apply the division lemma to 522 and 357, to get
522 = 357 x 1 + 165
Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 165 and 357, to get
357 = 165 x 2 + 27
Step 3: We consider the new divisor 165 and the new remainder 27, and apply the division lemma to get
165 = 27 x 6 + 3
We consider the new divisor 27 and the new remainder 3, and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 357 and 522 is 3
Notice that 3 = HCF(27,3) = HCF(165,27) = HCF(357,165) = HCF(522,357) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 626 > 3, we apply the division lemma to 626 and 3, to get
626 = 3 x 208 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 626 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(626,3) .
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) .
