Given numbers are 768, 770, 921, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 770) = 295680
GCD(768, 770) = ( 768 x 770 ) / 295680
= 768 / 770
= 768
Step2:
LCM(2, 921) = 1842
GCD(2, 921) = ( 2 x 921 ) / 1842
= 2 / 921
= 2
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 768, 770, 921, 778 is 1
