Given numbers are 573, 821, 782, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(573, 821) = 470433
GCD(573, 821) = ( 573 x 821 ) / 470433
= 573 / 821
= 573
Step2:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 573, 821, 782, 644 is 1
