Given numbers are 754, 225, 630, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(754, 225) = 169650
GCD(754, 225) = ( 754 x 225 ) / 169650
= 754 / 225
= 754
Step2:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 754, 225, 630, 649 is 1
