Given numbers are 405, 167, 784, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 167) = 67635
GCD(405, 167) = ( 405 x 167 ) / 67635
= 405 / 167
= 405
Step2:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
Step3:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 405, 167, 784, 124 is 1
