Given numbers are 987, 840, 954, 544
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 840) = 39480
GCD(987, 840) = ( 987 x 840 ) / 39480
= 987 / 840
= 987
Step2:
LCM(21, 954) = 6678
GCD(21, 954) = ( 21 x 954 ) / 6678
= 21 / 954
= 21
Step3:
LCM(3, 544) = 1632
GCD(3, 544) = ( 3 x 544 ) / 1632
= 3 / 544
= 3
So, Greatest Common Divisor of 987, 840, 954, 544 is 1
