Given numbers are 618, 686, 785, 535
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 686) = 211974
GCD(618, 686) = ( 618 x 686 ) / 211974
= 618 / 686
= 618
Step2:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
Step3:
LCM(1, 535) = 535
GCD(1, 535) = ( 1 x 535 ) / 535
= 1 / 535
= 1
So, Greatest Common Divisor of 618, 686, 785, 535 is 1
