Given numbers are 105, 237, 158, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 237) = 8295
GCD(105, 237) = ( 105 x 237 ) / 8295
= 105 / 237
= 105
Step2:
LCM(3, 158) = 474
GCD(3, 158) = ( 3 x 158 ) / 474
= 3 / 158
= 3
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 105, 237, 158, 640 is 1
