HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 707, 518, 492 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 707, 518, 492 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 707, 518, 492 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 707, 518, 492 is 1.
HCF(707, 518, 492) = 1
HCF of 707, 518, 492 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 707, 518, 492 is 1.
Highest Common Factor of 707,518,492 is 1
Step 1: Since 707 > 518, we apply the division lemma to 707 and 518, to get
707 = 518 x 1 + 189
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 189 and 518, to get
518 = 189 x 2 + 140
Step 3: We consider the new divisor 189 and the new remainder 140, and apply the division lemma to get
189 = 140 x 1 + 49
We consider the new divisor 140 and the new remainder 49,and apply the division lemma to get
140 = 49 x 2 + 42
We consider the new divisor 49 and the new remainder 42,and apply the division lemma to get
49 = 42 x 1 + 7
We consider the new divisor 42 and the new remainder 7,and apply the division lemma to get
42 = 7 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 707 and 518 is 7
Notice that 7 = HCF(42,7) = HCF(49,42) = HCF(140,49) = HCF(189,140) = HCF(518,189) = HCF(707,518) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 492 > 7, we apply the division lemma to 492 and 7, to get
492 = 7 x 70 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 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 7 and 492 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(492,7) .
