Given numbers are 679, 721, 278, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 721) = 69937
GCD(679, 721) = ( 679 x 721 ) / 69937
= 679 / 721
= 679
Step2:
LCM(7, 278) = 1946
GCD(7, 278) = ( 7 x 278 ) / 1946
= 7 / 278
= 7
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 679, 721, 278, 148 is 1
