Given numbers are 648, 565, 964, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 565) = 366120
GCD(648, 565) = ( 648 x 565 ) / 366120
= 648 / 565
= 648
Step2:
LCM(1, 964) = 964
GCD(1, 964) = ( 1 x 964 ) / 964
= 1 / 964
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 648, 565, 964, 515 is 1
