GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 778) = 335318
GCD(862, 778) = ( 862 x 778 ) / 335318
= 862 / 778
= 862
Step2:
LCM(2, 385) = 770
GCD(2, 385) = ( 2 x 385 ) / 770
= 2 / 385
= 2
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 862, 778, 385, 157 is 1
