Given numbers are 840, 748, 557, 476
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 748) = 157080
GCD(840, 748) = ( 840 x 748 ) / 157080
= 840 / 748
= 840
Step2:
LCM(4, 557) = 2228
GCD(4, 557) = ( 4 x 557 ) / 2228
= 4 / 557
= 4
Step3:
LCM(1, 476) = 476
GCD(1, 476) = ( 1 x 476 ) / 476
= 1 / 476
= 1
So, Greatest Common Divisor of 840, 748, 557, 476 is 1
