Given numbers are 798, 646, 552, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 646) = 13566
GCD(798, 646) = ( 798 x 646 ) / 13566
= 798 / 646
= 798
Step2:
LCM(38, 552) = 10488
GCD(38, 552) = ( 38 x 552 ) / 10488
= 38 / 552
= 38
Step3:
LCM(2, 309) = 618
GCD(2, 309) = ( 2 x 309 ) / 618
= 2 / 309
= 2
So, Greatest Common Divisor of 798, 646, 552, 309 is 1
