GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 658) = 63826
GCD(679, 658) = ( 679 x 658 ) / 63826
= 679 / 658
= 679
Step2:
LCM(7, 839) = 5873
GCD(7, 839) = ( 7 x 839 ) / 5873
= 7 / 839
= 7
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 679, 658, 839, 155 is 1
