Given numbers are 156, 320, 491, 763
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 320) = 12480
GCD(156, 320) = ( 156 x 320 ) / 12480
= 156 / 320
= 156
Step2:
LCM(4, 491) = 1964
GCD(4, 491) = ( 4 x 491 ) / 1964
= 4 / 491
= 4
Step3:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
So, Greatest Common Divisor of 156, 320, 491, 763 is 1
