Given numbers are 640, 104, 17, 130
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 104) = 8320
GCD(640, 104) = ( 640 x 104 ) / 8320
= 640 / 104
= 640
Step2:
LCM(8, 17) = 136
GCD(8, 17) = ( 8 x 17 ) / 136
= 8 / 17
= 8
Step3:
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
= 1 / 130
= 1
So, Greatest Common Divisor of 640, 104, 17, 130 is 1
