Given numbers are 122, 136, 803, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(122, 136) = 8296
GCD(122, 136) = ( 122 x 136 ) / 8296
= 122 / 136
= 122
Step2:
LCM(2, 803) = 1606
GCD(2, 803) = ( 2 x 803 ) / 1606
= 2 / 803
= 2
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 122, 136, 803, 640 is 1
