GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 772) = 54040
GCD(280, 772) = ( 280 x 772 ) / 54040
= 280 / 772
= 280
Step2:
LCM(4, 985) = 3940
GCD(4, 985) = ( 4 x 985 ) / 3940
= 4 / 985
= 4
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 280, 772, 985, 148 is 1
