Highest Common Factor of 35, 42, 77, 98 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 35, 42, 77, 98 i.e. 7 the largest integer that leaves a remainder zero for all numbers.

HCF of 35, 42, 77, 98 is 7 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 35, 42, 77, 98 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 35, 42, 77, 98 is 7.

HCF(35, 42, 77, 98) = 7

HCF of 35, 42, 77, 98 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 35, 42, 77, 98 is 7.

Highest Common Factor of 35,42,77,98 using Euclid's algorithm

Step 1: Since 42 > 35, we apply the division lemma to 42 and 35, to get

42 = 35 x 1 + 7

Step 2: Since the reminder 35 ≠ 0, we apply division lemma to 7 and 35, to get

35 = 7 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 35 and 42 is 7

Notice that 7 = HCF(35,7) = HCF(42,35) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 77 > 7, we apply the division lemma to 77 and 7, to get

77 = 7 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 77 is 7

Notice that 7 = HCF(77,7) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 98 > 7, we apply the division lemma to 98 and 7, to get

98 = 7 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 98 is 7

Notice that 7 = HCF(98,7) .
