Given numbers are 417, 645, 669, 206
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 645) = 89655
GCD(417, 645) = ( 417 x 645 ) / 89655
= 417 / 645
= 417
Step2:
LCM(3, 669) = 669
GCD(3, 669) = ( 3 x 669 ) / 669
= 3 / 669
= 3
Step3:
LCM(3, 206) = 618
GCD(3, 206) = ( 3 x 206 ) / 618
= 3 / 206
= 3
So, Greatest Common Divisor of 417, 645, 669, 206 is 1
