Given numbers are 280, 782, 271, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 782) = 109480
GCD(280, 782) = ( 280 x 782 ) / 109480
= 280 / 782
= 280
Step2:
LCM(2, 271) = 542
GCD(2, 271) = ( 2 x 271 ) / 542
= 2 / 271
= 2
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 280, 782, 271, 921 is 1
