Given numbers are 640, 665, 349, 586
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 665) = 85120
GCD(640, 665) = ( 640 x 665 ) / 85120
= 640 / 665
= 640
Step2:
LCM(5, 349) = 1745
GCD(5, 349) = ( 5 x 349 ) / 1745
= 5 / 349
= 5
Step3:
LCM(1, 586) = 586
GCD(1, 586) = ( 1 x 586 ) / 586
= 1 / 586
= 1
So, Greatest Common Divisor of 640, 665, 349, 586 is 1
