Given numbers are 640, 699, 918, 747
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 699) = 447360
GCD(640, 699) = ( 640 x 699 ) / 447360
= 640 / 699
= 640
Step2:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
Step3:
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
= 1 / 747
= 1
So, Greatest Common Divisor of 640, 699, 918, 747 is 1
