GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 286) = 56914
GCD(398, 286) = ( 398 x 286 ) / 56914
= 398 / 286
= 398
Step2:
LCM(2, 861) = 1722
GCD(2, 861) = ( 2 x 861 ) / 1722
= 2 / 861
= 2
Step3:
LCM(1, 525) = 525
GCD(1, 525) = ( 1 x 525 ) / 525
= 1 / 525
= 1
So, Greatest Common Divisor of 398, 286, 861, 525 is 1
