Given numbers are 975, 623, 420, 544
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(975, 623) = 607425
GCD(975, 623) = ( 975 x 623 ) / 607425
= 975 / 623
= 975
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 544) = 544
GCD(1, 544) = ( 1 x 544 ) / 544
= 1 / 544
= 1
So, Greatest Common Divisor of 975, 623, 420, 544 is 1
