Given numbers are 115, 945, 756, 513
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 945) = 21735
GCD(115, 945) = ( 115 x 945 ) / 21735
= 115 / 945
= 115
Step2:
LCM(5, 756) = 3780
GCD(5, 756) = ( 5 x 756 ) / 3780
= 5 / 756
= 5
Step3:
LCM(1, 513) = 513
GCD(1, 513) = ( 1 x 513 ) / 513
= 1 / 513
= 1
So, Greatest Common Divisor of 115, 945, 756, 513 is 1
