Given numbers are 420, 751, 526, 261
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 751 are 751
Prime factors of 526 are 2 x 263
Prime factors of 261 are 3 x 3 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 751, 526, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 751) = 315420
GCD(420, 751) = ( 420 x 751 ) / 315420
= 420 / 751
= 420
Step2:
LCM(1, 526) = 526
GCD(1, 526) = ( 1 x 526 ) / 526
= 1 / 526
= 1
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 420, 751, 526, 261 is 1
