GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(158, 402) = 31758
GCD(158, 402) = ( 158 x 402 ) / 31758
= 158 / 402
= 158
Step2:
LCM(2, 891) = 1782
GCD(2, 891) = ( 2 x 891 ) / 1782
= 2 / 891
= 2
Step3:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
So, Greatest Common Divisor of 158, 402, 891, 782 is 1
