GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(248, 548) = 33976
GCD(248, 548) = ( 248 x 548 ) / 33976
= 248 / 548
= 248
Step2:
LCM(4, 143) = 572
GCD(4, 143) = ( 4 x 143 ) / 572
= 4 / 143
= 4
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 248, 548, 143, 640 is 1
