Given numbers are 406, 174, 647, 185
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 174) = 1218
GCD(406, 174) = ( 406 x 174 ) / 1218
= 406 / 174
= 406
Step2:
LCM(58, 647) = 37526
GCD(58, 647) = ( 58 x 647 ) / 37526
= 58 / 647
= 58
Step3:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
So, Greatest Common Divisor of 406, 174, 647, 185 is 1
