Given numbers are 408, 634, 805, 945
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 634) = 129336
GCD(408, 634) = ( 408 x 634 ) / 129336
= 408 / 634
= 408
Step2:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 408, 634, 805, 945 is 1
