Given numbers are 148, 644, 355, 679
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(148, 644) = 23828
GCD(148, 644) = ( 148 x 644 ) / 23828
= 148 / 644
= 148
Step2:
LCM(4, 355) = 1420
GCD(4, 355) = ( 4 x 355 ) / 1420
= 4 / 355
= 4
Step3:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
So, Greatest Common Divisor of 148, 644, 355, 679 is 1
