Given numbers are 751, 660, 203, 490
The list of prime factors of all numbers are
Prime factors of 751 are 751
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 203 are 7 x 29
Prime factors of 490 are 2 x 5 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 751, 660, 203, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(751, 660) = 495660
GCD(751, 660) = ( 751 x 660 ) / 495660
= 751 / 660
= 751
Step2:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 751, 660, 203, 490 is 1
