Given numbers are 646, 416, 825, 761
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 416) = 134368
GCD(646, 416) = ( 646 x 416 ) / 134368
= 646 / 416
= 646
Step2:
LCM(2, 825) = 1650
GCD(2, 825) = ( 2 x 825 ) / 1650
= 2 / 825
= 2
Step3:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
So, Greatest Common Divisor of 646, 416, 825, 761 is 1
