Given numbers are 130, 695, 518, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 695) = 18070
GCD(130, 695) = ( 130 x 695 ) / 18070
= 130 / 695
= 130
Step2:
LCM(5, 518) = 2590
GCD(5, 518) = ( 5 x 518 ) / 2590
= 5 / 518
= 5
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 130, 695, 518, 665 is 1
